Bogotá’s Evidence-Based Approach to Empowering Caregivers

Project Type:
Community Engagement, Equity, Health and Wellbeing, Technology

At a Glance


The district administration built 21 Care Blocks, community centers that have provided support to more than 180,000 female caregivers and their families since January 2022.


Since its inception, the services of the Bogotá Care System have improved the lives of more than 546,500 women and their families. In 2023, it helped more than 550 women receive their high school diploma.


Through the Bogotá Public Innovation Laboratory – iBO, the Care Blocks are implementing new registration technology through a chatbot. The first stage managed to integrate more than 2,400 women to the system.


They successfully combined the use of data and feedback from residents to build a social support program that promotes economic mobility.

In a pioneering initiative aimed at supporting caregivers, Bogotá has successfully established 21 community centers throughout the city called Care Blocks.

During a visit from the What Works Cities Certification team to a Care Block in the Manitas neighborhood in the town of Ciudad Bolívar, which is considered a vulnerable area, the impact of the program was evident. As people danced and celebrated the Care Block’s third anniversary, caregivers expressed gratitude for the opportunity to receive support to improve their lives.

Care Blocks are designed to relieve the responsibilities and stress of caregiving. The goal is to allow caregivers to focus on other essential aspects of their lives that often get pushed aside due to their duties. All services provided are free, including community laundries. With these, more than 14,700 hours of care work were freed up for women, equivalent to 616 days.

According to the District Secretariat for Women, since January 2022, more than 180,000 female caregivers and their families have participated in the Care Blocks.

The District is actively involved in improving the program. Thanks to the Bogotá Public Innovation Laboratory – iBO, they are developing a system to register people in various activities offered in the Care Blocks, using a recently implemented chatbot to address queries and facilitate registrations. There are more than 2,100 engagements with the chatbot.

The results for residents and the emphasis of digitization and data have attracted the attention of leaders across the city and the country as a model to improve the lives of residents. Efforts are underway to conduct a comprehensive impact assessment and increase outreach.

Bogotá’s pioneering initiative highlights the cultural evolution around care. This model is proving to be a catalyst for positive change in the lives of caregivers throughout the city and a reference for other cities to follow.

“Here we can continue studying and fulfill our dreams. We [caretakers] are always told: ‘This is going to inhibit you and you will not be able to move forward,’ but this program really helps us a lot.”

Tatiana Guayara, San Cristóbal Care Block beneficiary (quote provided by the City)

“With this Certification it is evident that Bogotá has put data, technology and innovation at the center of government decisions on critical issues such as the District Care System, the environment and mobility. Our commitment is to continue with this effort, build on what has been built and continue promoting a conscious, responsible and strategic use of information to improve the quality of life of citizens.”

15% drop in violence in neighborhoods covered by COMPAZ, more significant when compared to levels of violence throughout the City.


E.I.T.A! Recife, a City-run innovation lab, elevates and experiments with resident solutions to City challenges. More than 660,000 have tested these solutions.


Through an initiative to enable experimentation with digital solutions, the City reduced the time by 70% necessary to implement new solutions.


Development of a vaccination app for COVID-19 that registered 1.6 million users and allowed residents to receive vaccines in an orderly and safe manner, especially compared to vaccine uptake in Brazil overall.


It received resources for climate adaptation via a credit operation with the IDB, which will allow Recife to invest US$364 million in a social, territorial and climate justice initiative called ProMorar. It will be the largest urban resilience program in Brazil and guarantees decent housing for more than 150,000 people.

With an air of historic architecture and an incubator for startups and innovative research, Recife, Brazil, stands out for connecting tradition, modernity and technological expertise. However, Recife has historically had one of the highest levels of income inequality in the country, one of the main factors contributing to conditions that have led to high crime rates in the city. Ranked as the 22nd most dangerous city in the world, Recife recorded 55 homicides per 100,000 inhabitants in 2017.

To combat this violence, as well as drug trafficking, the City drew inspiration from other cities, even traveling to Medellín, Colombia (which successfully implemented a similar project) more than 40 times, to formulate and launch an innovative community center project, COMPAZ. COMPAZ offers a wide range of quality programs and services, from math classes to martial arts classes, to support crime and violence prevention efforts.

With COMPAZ, the city leverages neighborhood-level data and evidence to find and implement solutions by and for communities. Thus, Recife equitably and efficiently supports needy neighborhoods, addressing issues such as public safety and economic mobility with localized and targeted interventions.

“This helps us legitimize the vision that Recife has…when we make data-driven decisions, it leads us to the right solution. We have scarce resources, we need to prioritize allocation and maximize impacts. How can I reach more people with fewer resources?”

João Henrique Campos, Mayor

Data-driven decision making is an integral part of COMPAZ. Using Recife’s open data portal, the city’s evaluation policy unit collaborates with academic institutions to collect data and evaluate program effectiveness, enabling the development of evidence-based policies and programs that provide solutions to issues revealed by the data. The results speak for themselves, with a 15% drop in violence in a COMPAZ neighborhood within four years of starting the project — a significant improvement over the city level, which remained stagnant during that same period.

Recife is not only implementing evidence-based programs like COMPAZ, but it is also at the forefront of innovation. That includes urban space in the city in a testing environment for innovations, making Recife the largest urban open innovation laboratory in Latin America, with an area of 218km². Open Innovation Cycles allow solutions developed by startups to be accelerated by the City Hall through a special contractual regime.Open Innovation Cycles recognize that there are challenges that the public sector cannot achieve alone – transformative solutions must be built with the end user, the resident. The ultimate goal is a city with more equal opportunities for everyone. So far, these innovation cycles have developed:

  • (I) algorithm for completing the electronic medical record integrated into public health systems;
  • (II) software for managing queues for free public health consultations and medical examinations; It is
  • (III) Internet of Things (IoT) sensing for flooding and rain in regions susceptible to disasters to generate real-time alerts and create operational protocols.

The population is at the center of innovative data-driven solutions in Recife. This approach allowed us to tailor policies and programs to the specific needs of the community, using data to determine where resources are most needed and identify opportunities for success.

“We are not reinventing the wheel, we are eager to learn from other cities, from other teams. What works for other cities, we try to adapt to ours.”

Data and a Cross-Sector Approach Lead to Street Safety in Carlsbad.

Project Type:
Community Engagement, Finance, Health and Wellbeing, Infrastructure, Public Safety, Transportation

2024 Gold Certification


Carlsbad, California, achieved a 73 percent decrease in homelessness among veterans by leveraging data in new ways. A key to success was maintaining real-time personalized data on veterans experiencing homelessness, and using that information to catalyze collaboration among service providers to get veterans into permanent housing. The City also adopted its first “data service standard” aimed at making sure that new data products are designed to be as useful as possible for city leaders, residents, and others who may benefit.

2023 Silver Certification


Using road collision heatmaps and other data to inform interventions, the City saw a 19% decrease in all injury collisions.


Monitored progress and changed course when needed to achieve traffic goals using Performance & Analytics strategies.


City’s staff telecommuting policy reduced employee commute time by 47,000 hours and saved the City between $300,000 – $400,000. It has also improved traffic conditions for all city residents and eliminated 424 metric tons of greenhouse gas emissions.


Budget and finance processes require data and alignment with the city’s 5-Year Strategic Plan, to ensure funds are efficiently and effectively allocated to address the most important priorities of the community.

The number of collisions involving bikes and e-bikes was already surging in Carlsbad when, in August 2022, two bikers were killed during a 10-day period. The City had issued an ordinance on e-bike safety a few months before, but the tragedies and an alarming 233% increase in collisions involving bike and e-bikes between 2019 and 2022 promoted greater action. City Manager Scott Chadwick declared a 6-month local emergency, which was ratified by the City Council at its next meeting. The emergency allowed the City flexibility to move quickly and focus resources on encouraging everyone to be safer on the road.

Some residents worried that the emergency declaration would lead to less access for bikes or more traffic. But Chadwick was able to reassure them. “We’re going to let the data guide us,” he said. And that is exactly what they did.

Immediately after declaring the emergency, the City began gathering and analyzing additional data on collisions. They created heatmaps to identify the most dangerous intersections, did a 5-year trend analysis, and set up tracking for the future. Armed with data and streamlined procurement processes as part of the emergency declaration, the City was painting key intersections and bike lanes with high-visibility green paint within two weeks. In fact, they moved so fast that they exhausted the supply of green paint in the region.

Within 30 days of the emergency declaration, the City had a full plan in place for improving street safety. The Safer Streets Together Plan seeks to change public behaviors and attitudes by focusing on education, engineering and enforcement. “It wasn’t just, ‘Here’s an emergency.’ The public saw real things happening in the first weeks and months and that’s how this has changed things so quickly,” Chief Innovation Officer David Graham said.

Six months after declaring an emergency, injury collisions across all transportation modes were down by 19% compared to the same time period in the previous year, and injury collisions related to bikes and e-bikes had decreased 13%. Graham points to qualitative measures of success as well – street safety yard signs and car window clings on display throughout the community, residents saying they are wearing helmets and slowing down, and the city’s partnerships with schools and bike organizations.

Because of the positive trends and evidence of behavior change, in March 2023 the City Council voted to extend the emergency declaration for a few more months. City staff hope that a year’s worth of data and analysis will help build a sustainable approach to traffic safety and that the early positive trends will become permanent.

The traffic safety emergency is not the first emergency that Carlsbad has tackled with data-driven decision making. It took a similar and equally successful approach during COVID. Hopefully the City won’t have cause for testing its emergency response again anytime soon, but having a well-honed system for collecting and analyzing data, and for innovating and tracking outcomes means that no matter what the future holds, Carlsbad will be well prepared to handle it.

“To see transformation in government you have to invest in areas that aren’t readily apparent like data and analytics, process improvement and operational excellence. When we work together with our community to discover shared insights around issues like traffic safety, we can create impactful change.”

David Graham, Chief Innovation Officer

It’s not easy to change the way people behave on the road. Often, you’re trying to change habits people have had for years or decades, for better or worse. By taking a balanced approach to traffic safety and digging into the data, we can see what’s working and what isn’t working, and learn how to be more effective as we move forward.

Proving That Smooth Data Practices Translate to Smooth Traffic

Project Type:
Community Engagement, Infrastructure, Public Safety, Transportation

2024 Gold Certification


Montevideo, Uruguay marshaled data to keep residents safe during a recent drought and water crisis. As salinity levels in tap water spiked, city leaders publicly shared water-test data daily, enabling pregnant women, people with hypertension, and others to know when water was safe to drink. They also used data to identify vulnerable populations who would benefit most from fresh water deliveries. This work built on a major push to build a culture of data-driven decision making in City Hall; staff were offered a financial incentive for scaling data and evidence practices which moved the city to Gold Certification.

10 transit intervention plans created for hotspot traffic areas.


Reduced annual traffic fatality rate to 6.2 per 100,000 residents—half the country’s overall rate.


Used strong Data Management practices to develop impactful traffic interventions with real-time data.

In recent decades, the leaders of Montevideo, Uruguay, have become familiar with a simple fact with far-reaching consequences: more people means more vehicles. As Uruguay’s commercial, political and cultural hub, Montevideo is no stranger to traffic. In 2015, its leaders set out to address the City’s massive traffic problem in a data-driven way. The City installed dozens of real-time sensors along major routes, created a new Center for Mobility Management to monitor and manage traffic data collection, and implemented a new mobility plan to cool off hotspots.

After building a data visualization platform that displays real-time traffic levels across Montevideo’s road network, and holding neighborhood meetings to understand residents’ traffic concerns, the City focused transit interventions on 10 particularly congested hot zones. Leaning heavily on sensor data analyses, they simulated the impact of different traffic engineering solutions—such as changing the timing and duration of traffic signals, or making a street one-way—and then settled on the most impactful options for each site. This access to high-quality, real-time data, combined with strong data governance practices, allowed the City to better understand the problem and then to develop and test tailored solutions for the hotspot zones.

“We don’t want to collect information just to verify the reality, we want to collect information to change the reality.”

Carolina Cosse, Mayoress

In addition to real quality-of-life improvements for Montevideo drivers, the City also realized environmental benefits, including reduced CO2 emissions, due to less idling, and better fuel economy. Moreover, the City’s commitment to improving traffic flow is helping to save lives. Montevideo’s annual traffic fatality rate is now 6.2 per 100,000 residents—half the country’s overall rate. City leaders believe that the installation of speed radars across the City, along with efforts to lower congestion in hotspots, has helped change driver behavior and prevent traffic-related deaths.

When you can measure a problem, you can manage it—and that’s exactly what Montevideo officials are doing, street by street.

“For us, What Works Cities Certification is a way to measure our performance. The goal isn’t to be happy with where we are now—although we’re proud of our progress—but rather to evolve and provide better services to residents.”

Data-Driven Approach Cuts Traffic Deaths by 57%.

Project Type:
Community Engagement, Infrastructure, Public Safety, Transportation

At a Glance


Reduced traffic fatalities by 57% over 10 years (2012-22)


1,086 lives saved


Eight consecutive years of fatality reductions


Mayor José Sarto signed a commitment to reduce fatalities by another 50% in the next 10 years


Monitored progress and changed course when needed to achieve traffic goals using Performance & Analytics strategies

At a recent public hearing on traffic accidents in Fortaleza, everyone participating shared that they knew someone who had lost their life or was critically injured in an accident. With 5 million daily trips and 29% of motorists on motorcycles, traffic fatalities have been an unfortunate part of life for Fortaleza’s 2.6 million residents.

In 2012, Fortaleza took action. Starting with historic traffic data, the City set goals and made evidence-based decisions about speed limits and traffic patterns. In 2021, it launched the Vida platform to consolidate traffic data from varying institutions and make it publicly accessible.

With these performance management and data-driven approaches, the City reduced traffic fatalities by 57% over 10 years. Additionally, the City established a road safety committee that meets every 15 days to review crash data and predictive analysis, using it to adjust strategies. The first city in Brazil to have a municipal road safety plan as law, Fortaleza has saved 1,086 lives and saved the City close to $42 million Brazilian Reals ($8.3 million USD).

“All of our actions, everything we do, is based on data and evidence.”

Elcio Batista, Vice Mayor

Still, Mayor Sarto is acutely aware that the City saw 158 traffic deaths in 2022, and he is committed to reducing fatalities by another 50% by 2031.

Fortaleza’s aim to realize Vision Zero—an international program working to eliminate all traffic fatalities and severe injuries—is just one of the data initiatives that has helped the City achieve What Works Cities Gold Certification. With its focus on data, the City has reduced school dropout rates, digitized its construction permitting process and launched an app to track sexual harassment on public transit. Fortaleza has also made progress on building a data culture: They developed a clear governance structure to coordinate data use, launched an Open Data Plan to guide data oversight, and concentrated over 200 datasets from 28 organizations in an Open Data Portal. By making so much City data publicly available, the City is promoting informed decision-making, transparency and robust resident engagement.

Vice Mayor Elcio Batista sees even more progress on the horizon. “Being Certified makes me proud and hopeful. Proud of what we have accomplished and hopeful for what is still to come.”

“By achieving Certification, it shows we are trying to do things the right way. It’s an honor for us, for the team, and it gives us a passport for the future.”

Public Policies Based on Data Lead to Significant Decrease in Infant Mortality

Project Type:
Health and Wellbeing, High-Performing Government, Youth Development

At a Glance


39% decline in the infant mortality rate between 2016 and 2022.


15 minutes: the maximum time it takes for a resident to reach a community healthcare center.


300 individual metrics are being tracked to support the quality and reliability of 115 public services.


100% of Buenos Aires community health centers now operate with electronic medical charts.


The City now has a thorough data strategy, clear evidence-based policies, 30 executive dashboards, and more than 4,300 indicators after creating the Undersecretariat for Evidence-Based Public Policies and the General Directorate of Monitoring and Evaluation.

Reducing the Infant Mortality Rate

Improving the infant mortality rate in Buenos Aires, which was 7.2 deaths per 1,000 live births in 2016, required a multi-pronged strategy, especially because the hospitals and doctors offices are run by public and private entities as well as social security. Additionally, the strategy was not just medical—it required the coordinated approach of the Ministry of Health and the Ministry of Human Development and Habitat to carry out policies that considered both medical and social implications.

Effective solutions to complex and urgent problems require more than passion and good ideas. City leaders need the right data to illuminate the depth and breadth of an issue; that is what sets the stage for smart public policy.

Horacio Rodríguez Larreta, Mayor

The City, which had already worked to build a data-driven culture, took another step forward by implementing electronic medical records in all health and community action centers (CeSACs), collecting healthcare data from across Buenos Aires to better identify at-risk pregnant women and develop integrated interventions to both strengthen health services and create targeted solutions. Specific goals were established:

  • Make healthcare more accessible so that every resident has a community healthcare center less than 15 minutes from their home.
  • All women would receive at least five checkups over the course of a pregnancy and seven pediatric consultations during the baby’s first year.
  • Promote the healthy development of vulnerable children between 45 days and 3 years old through 76 early childhood centers.

With these clear, measurable targets and the increase in higher quality data, all of the goals had been reached by 2022. Additionally, the City reached their goals with an emphasis on transparency: Buenos Aires’ General Directorate of Statistics and Censuses allowed residents to have transparent and reliable access to data as well as a way to monitor and evaluate progress on the measures the City was taking to improve healthcare.


How else has Buenos Aires become a more data-driven government? 

  • Digitized and streamlined their procurement system and made data on city contracts open and accessible.
  • BOTI, the first city-developed chatbot for WhatsApp in the world, had 59 million conversations with residents in 2022. 
  • Developed “green streets” to create more natural space for pedestrian enjoyment and capture stormwater.
  • Created a 3D model of the City to aid neighborhood development and make it easier to see regulations and codes. 

The Ministry of Health constructed seven new health care centers and renovated 10 others. Pregnant women were given priority when making appointments online for primary care visits. Targeted campaigns involving workshops, at-work training and seminars—on subjects including sleeping and eating habits—had reached 7,000 families considered to be highly vulnerable. And the overall impact was clear: The City of Buenos Aires reduced its infant mortality rate by 39% from 7.2 deaths per 1,000 live births in 2016, to 4.4 deaths per 1,000 live births in 2022. 

Buenos Aires’ progress on maternal care and infant health is just one example of how the City’s commitment to improve data quality, quantity and practices is bearing fruit. But a 39% decrease in infant mortality rate is more than a success story for the City of Buenos Aires—it’s a number that represents the prevention of heartbreaking losses in scores of families—and incalculable joy as families watch their children grow up.  

We have a limited time to transform reality—and data-driven governance can accelerate positive change. By having shared standards and rules for data management, we create a common understanding and language, powering day-to-day change.”

Established a team of research scientists who deliver data-driven insights and analysis to inform District policymakers.


Increased data transparency with residents by publicizing CapSTAT meetings, welcomed online public opinion on data policy, and built feedback loops monitoring solutions.


Developed a command center within the Metropolitan Police Department that uses real-time data to analyze similar crimes, trends, and background for detectives in the field, which helped decrease all crime by 11% and violent crimes by 22%.


Analyzed data from resident interactions with the 311 system to eliminate inefficiencies, allowing the District to implement measures that have achieved a 90-second response time for 85% of calls made to 311.

More Than the Nation’s Capital

Whether it’s enabling residents to send text messages to 911, establishing a leading “open by default” policy for all District government data, or establishing a unique, in-house team of data scientists, Washington, DC, is using technology and data to improve its delivery of services and outcomes for residents.

“In the District, we expect our agencies to engage in fact-based decision-making. We understand that our decisions affect the lives of our nearly 700,000 residents, and we always want to know how well our policies and programs are working so that we have the opportunity to learn and adjust while we act. As we continue building a safer, stronger, and more resilient DC, we will continue to use data and scientific thinking to improve our day-to-day operations and deliver good government.”

Washington D.C. Mayor Muriel Bowser

As part of her commitment to data, Mayor Bowser charged City Administrator Rashad Young to stand up The Lab @ DC, a team of applied research scientists who use data and scientific insights and methods to provide timely, relevant, and high-quality analysis to inform the District’s most important decisions. The Lab completed the District’s high-profile study of the impact of body-worn cameras on policing, and it is now studying the effectiveness of the District’s rat abatement program. While these two subjects are very different, they demonstrate the capacity of data to inform a range of decisions.

The District’s in-house team of data scientists, The Lab @ DC, recently tested the effects of police body-worn cameras.

Monitoring how agencies collect and use data is part of quarterly cluster performance meetings hosted by the Office of Budget and Performance Management. As part of these sessions, City Administrator Young reviews progress toward milestones and mayoral priorities along with the agencies’ implementation of data-based decision-making as part of their internal processes. The sessions also provide agencies with an opportunity to showcase successes and lift up obstacles.

“Managing a $13 billion, 35,000-person government is nearly impossible without accurate metrics to lead our decisions. These quarterly sessions ensure we are being good stewards of District resources, that we are keeping our commitments, and that we are evaluating and redirecting if our approaches are not rendering quality results.”

City Administrator Rashad Young

During a quarterly cluster meeting last year, reviews of the 311 system revealed that there were no standard definitions of open and closed cases across city agencies, no standard response times, and in certain instances, it was taking more than four minutes for calls to be answered. The agency was charged with developing a plan to address the significant lag times. After hiring additional staffing and providing extensive training as well as additional outlets for contacting 311 (via text and a smartphone application), the agency was able to achieve a 90-second response time, 85 percent of the time.

“Mayor Bowser and City Administrator Young embrace the use of data across our government agencies. This expectation motivates agencies to be on the ready with sound, reliable data to support program recommendations and initiatives. Agencies also understand that much of their data is now publicly accessible through our open data laws.”

Director of the Office of Budget and Performance Management Jennifer Reed

In April 2017, Mayor Bowser announced the signing of an executive order, creating a new policy that set an “open by default” standard for all District government data, including a directive to treat the City’s data as a valuable resource. The policy was based on recommendations made by What Works Cities partner the Sunlight Foundation, and provides a framework to make government more transparent and open while improving the quality and lowering the cost of operations.

The District has extended its commitment to data transparency by inviting residents to view the budgeting process, welcoming public opinion on its data policy, and building in feedback loops so that residents know when their problems have been addressed. The Mayor’s CapSTAT meetings — data-driven management tools designed to tackle timely policy issues and processes with analysis, mapping, business process reviews, and best practices — are also videotaped and shared with the public.

The Metropolitan Police Department embraced the use of data in past years as a tool for improving public safety. The Joint Strategic and Tactical Analysis Command Center pulls together real-time, robust analyses of similar crimes, trends, and background for detectives in the field. The department recently reported an 11% decrease in all crime, which includes a 22% decline in violent crimes.

“We’re delivering people the services they want and improving service delivery.”

City Administrator Rashad Young

City Administrator Young says, attributing the City’s use of data for much of that progress. Agencies ask for help unraveling particular challenges, and data and performance management experts are assigned to assist. For multifaceted challenges, resources from The Lab may be assigned to analyze the challenge and the path forward. Recently, the Department of Consumer and Regulatory Affairs experienced such a challenge when working to make the permitting process more efficient.

While data may not tell the full story, it gives agencies and decision-makers valuable insight into the District’s toughest challenges. City Administrator Young noted, “Fully utilizing data and evidence is the only way to really manage and have a rational sense of what you’re doing. Anything less feels random, and without context.”

2023 Platinum Certification

  • Launched Vision Zero, a data-driven traffic safety initiative with a goal to achieve zerofatal and serious injury crashes. The Vision Zero task force is composed of over 50 stakeholders including city departments (police, transportation, fire) and community stakeholders (Arizona State University, school districts, public health agencies) that conducted an analysis of crash data for the years 2012 through 2017. Using that data, the task-force created 37 transportation safety strategies, including the creation of four safety corridors based on statistical analysis of a higher propensity for collisions, plans for new road infrastructure, and community outreach plans.
  • Uses a performance-led budget process based on metrics, and resident and business satisfaction surveys. For example, following an increase in emergency service calls in the Salt River Bottom, an area with significant natural hazards and a large homeless population, an Incident Management Team was launched. In 2023, the City achieved several of its goals, including 66% of people engaged accepting shelter services and 52 tons of debris and over 3,200 tons of vegetation were removed. Based on these initial results, new, recurring funding has been allocated to support the City’s high priority “community health & safety” metrics.

Compiled data from the city’s sewage system monthly to track community drug use patterns and understand the depth of opioid use.


Using this data, monitored areas with high opioid use and deployed emergency response resources and abuse prevention interventions to hotspots accordingly.


Utilized similar wastewater testing data and tracking methods to monitor COVID-19 levels and identify outbreaks.

The Desert City’s Approach to Data

Like so many other cities in the country, Tempe, Arizona has been deeply affected by the opioid abuse crisis. The desert city of nearly 200,000 is part of Maricopa County, Arizona’s most populous area. This county also has the highest number of opioid-related deaths in the state.

As this public health emergency became more devastating in Tempe and around the country, Tempe’s leaders realized they needed to step up in two ways. First, they needed to be transparent about the severity of the problem facing the community. Second, they needed to create innovative solutions to help stem the opioid epidemic.

In 2018, the Strategic Management and Diversity Office, in partnership with ASU’s Biodesign Institute, submitted a proposal to the Tempe City Council Innovation Fund. The proposal focused on using wastewater to track the presence of opioid metabolites at the community level. City leaders supported the idea with innovation funds and began a partnership with ASU to tap this unlikely resource for data and to better inform decisions. Today, Tempe is on the cutting-edge of opioid abuse prevention work in the United States and has expanded this partnership to gather data on the presence of COVID-19 in the community.

“Cities may not want to call attention to opioid overdoses or abuse in their community,” said Wydale Holmes, a strategic management analyst in the city’s Strategic Management & Diversity Office.

“In Tempe, we’re courageously saying, ‘Yes, we have that, but we’re also doing something about it.’

It turns out that sewage offers an abundance of public health-related data — including a community’s drug consumption patterns. Tempe leverages its wastewater to identify areas of the city with elevated levels of opioid compounds — and then deploys emergency response resources and abuse prevention interventions to hotspots accordingly. All of this aligns to one of Tempe’s performance measures: ending opioid-related abuse and misuse by 2025, as measured by the percentage of 911 calls likely related to the drugs.

“Tempe is committed to data-informed community solutions. This first of its kind city model using wastewater-based epidemiology data informs strategic policy and operational decisions to advance community health.”

Director of the Strategic Management and Diversity Office Rosa Inchausti

It’s great to have data, but if you’re not doing anything with it or connecting it to resources and strategies for change, then it’s just information.”

Strategic Management Analyst Wydale Holmes

A New Diagnostic Matrix

Testing wastewater for real-time information about key markers of public health — everything from viruses to food contaminants to drug compounds — has been around for decades. But the approach is relatively uncommon in the United States. And no other city is trying to map the needs of residents around the opioid abuse epidemic in this way, said Dr. Rolf Halden, a professor at ASU’s Biodesign Center for Environmental Health Engineering.

“The United States is behind Europe. Every community that has done this work has not abandoned it, which is a testament to how well it works and how successful it is,” said Dr. Halden, who leads the wastewater data collection project in partnership with the City of Tempe.

Here’s how the wastewater analytics project helps the city identify opioid abuse hotspots and deploy resources strategically. Dr. Halden’s team takes raw sewage samples directly from five collection areas of the city for seven consecutive days each month. The scientists then test for four different types of opioids: fentanyl, heroin, oxycodone, and codeine.

After processing the samples, the ASU team hands off data to Tempe’s Enterprise GIS and Analytics team. The city can see where elevated levels of the four opioids are, and whether the opioids were metabolized or improperly disposed of. But the data contain no personally identifiable information — there is no way to tie data to specific addresses, neighborhoods or businesses.

All data are then published on the public Tempe Opioid Wastewater Collection Dashboard, created and maintained by Dr. Stephanie Deitrick, Tempe’s Enterprise GIS Manager. Through this dashboard and the Opioid Abuse Probable EMS Calls Dashboard, the information is analyzed by a multidisciplinary team, including Tempe’s Fire Medical and Rescue Department, to determine needed interventions. For example, if the data show a rise in opioid use among people under 18 in one area, the city might ramp up in-school outreach efforts. If one area suddenly becomes a major hotspot, the Tempe Fire Medical and Rescue Department can decide which emergency medical services and overdose prevention resources to move or increase to that area.

After implementing interventions, city officials can then track their potential effectiveness by monitoring changes in wastewater data alongside the EMS calls data. It’s a data feedback loop enabling the city to target its efforts — and, hopefully, prevent abuse and deaths.

“Dashboards allow people to quickly see overall trends within the data and to understand who is being impacted and where. Providing context is key when providing data to inform decision-making.”

Enterprise GIS Manager Dr. Stephanie Deitrick

Building a Data-Driven Culture

From its outset, the wastewater analytics project was directly tied to Tempe’s performance measure of ending opioid-related abuse and misuse. The Mayor, City Council, and City Manager set the expectation that reducing calls for opioid misuse or abuse was important to the executive leadership, and that both the goal and the performance measures supporting it needed to be shared internally with the City Council and administrative staff, community partners and externally to residents.

“Whatever we do, we always approach our employees and explain it to them and take the time to have the conversations about what we’re doing and why,” Tempe City Manager Andrew Ching said. “Every job has a purpose, and that job and that purpose exist within the framework of our strategic priorities and performance measures.”

City leaders also worked to communicate their efforts around the opioid abuse epidemic to the general public. The City of Tempe held an Opioid Town Hall in February 2019 to detail the wastewater project partnership and the types of support that Tempe provides to its residents struggling with opioids, their families and caregivers.

Anyone can visit the wastewater data dashboard and the Opioid Abuse Probable EMS Call Dashboard, designed and conceptualized by Dr. Deitrick and her team. The latter dashboard, which launched in 2018, gives Tempe Fire Medical and Rescue Department and the public a window into opioid abuse in the community. It details when calls related to abuse occurred, along with patients’ ages and genders, and the number of times Narcan/Naloxone overdose reversal medication was used during opioid-abuse related emergency calls.

Together, both dashboards inform Tempe officials’ efforts to end opioid misuse and abuse in the city, and help first responders and public health agencies on the ground see the impact of the targeted outreach and other interventions. It’s too early to tell how quickly the city will advance toward its goal — it was officially set in December 2019, when the baseline percentage of opioid-related EMS calls was 3.74 — but the right approach to data is in place to drive progress.

As the COVID-19 pandemic took hold around the world and in Tempe, city leaders have once again partnered with ASU wastewater researchers and are using this data in the same manner as the opioid data. The city is following the data to find areas of greatest need and is directing resources to help.

Seattle: Transforming a City in Fast-Moving Transition.

At a Glance


Initiated a data-driven approach to homelessness intervention that reoriented providers’ thinking — and their service delivery models — around the goal of ensuring any experience of homelessness in Seattle is rare, brief, and one-time.


Used a results-based contracting approach to monitor contract progress and encouraged contract managers and providers to meet regularly to review performance data.


Developed a dashboard focused on homelessness-related data from twelve departments to have better situational awareness of the homelessness crisis, in addition to how human services programs are performing.

Seattle is More than a Cup of Coffee

Fast-paced economic development is bringing plenty of high-tech jobs to Seattle and leading to spikes in household incomes, but progress isn’t being felt by everyone. It’s also contributing to a severe shortage of affordable housing and a homelessness crisis that led the City to declare a state of emergency in November 2015. This wasn’t for a lack of funding directed toward the city’s most vulnerable residents; Seattle’s budget for homeless services grew from $29 million in 2005 to $50 million in 2016 while homelessness continued to rise. Struggling to keep up, the City had to take a hard look at how it was tackling the crisis.

In response, the City launched its Pathways Home plan to shift its focus away from emergency, short-term interventions toward longer-term solutions, using data-driven decision-making to guide the way. As the City says, “Every dollar spent on emergency beds is a dollar not spent on strategies that allow people to exit homelessness.” A critical aspect of the plan was to rethink relationships with outside providers that contract with the City’s Human Services Department (HSD) to provide homelessness services, beginning with a pilot of $8.5 million worth of contracts. The pilot was carried out as part of Seattle’s engagement with What Works Cities partner the Government Performance Lab at the Harvard Kennedy School.

George, Maria, and their young son are among families that nonprofits contracted with the City have helped to move into permanent housing.

Through the pilot, providers were no longer tracking indicators like how many beds were filled or meals were distributed, but rather metrics such as how many people moved into permanent housing or became homeless again after being served, and how long they experienced homelessness. The approach reoriented providers’ thinking — and their service delivery models — around the goal of ensuring any experience of homelessness in Seattle is rare, brief, and one time. By using a results-based contracting approach, that’s what the City began holding providers accountable for too; contract managers and providers began meeting regularly to review performance data, enabling the City to troubleshoot problems in real time and spread the most effective practices.

“It’s not just about more money, although more resources is important. It’s also about thinking and how we do our work differently. How do we use data in a way that is not just compliance-driven, but helps us figure out what is working for people we’re trying to support out of crisis?”

Human Services Department Director Catherine Lester

Seattle has just expanded the pilot to $34 million in contracts awarded to bidders following the issuance of the City’s first competitive RFP for homelessness services in ten years. By keeping providers on target with performance benchmarks, the City aimed to double the number of people being moved into permanent housing by the end of 2018. Seattle is also expanding the performance-based model even further — across the entirety of HSD, which invests $105 million in contracts annually. Simultaneously, the City is developing a dashboard that will bring together homelessness-related data from twelve departments to have better situational awareness of the homelessness crisis, in addition to how human services programs are performing. Soon, real-time data will be available to staff, enabling a more coordinated, citywide approach to tackling the problem, tracking vendor performance, and more.

These efforts are part of a larger culture of data use throughout City Hall. Seattle was one of the first cities in the country to pursue open data and has a robust approach to engaging residents that goes beyond simply publishing data sets on its open data portal. The City is also advancing skills it developed with What Works Cities partner the Center for Government Excellence at Johns Hopkins University by rolling out performance management citywide. To help facilitate that process, the City’s Office of Performance is conducting twelve-week engagements with departments on a rolling basis to train staff. “Getting people the right resources — that’s what’s critical to getting the job done,” says former Organizational Performance Director Tyler Running Deer, who also worked extensively to help departments link their performance and budgeting goals. Seattle is also sharing progress toward citywide goals via its performance portal, one of several public-facing ways residents are kept informed.

After data showed that use of a former bikeshare program wasn’t offsetting its cost or meeting users’ needs, the City piloted a dockless model.

By tracking data and seeing what works, Seattle is learning important lessons about when and how to allocate funding, manage programs, or sometimes, when to shut them down. In one recent example, the City rolled out a bike share program, but data showed use wasn’t offsetting the cost and the service wasn’t meeting users’ needs. Bike docks were taking up valuable parking space, much to the dismay of local business owners. A highly-used station was located on a hilltop, so users weren’t returning the bikes, leaving the task to a truck that drove large numbers of bikes back to the dock at the end of each day. Now the City is piloting a dockless model with three different companies that are funding the program through their own revenue, and had to provide a data-collection plan before receiving permitting. Users can take the new bikes on the routes they truly travel and park them in more convenient locations. Without the temptation to concentrate docks in the highest-income areas, the hope is that bike access will also become more equitable. So far, the results seem promising, but for this city, there’s more than time that will tell — there’s also data.

2023 Gold Certification Highlight:


For several years the City of Scottsdale has been tracking and monitoring short-term rental properties and complaints about them. In 2022, the Arizona Legislature passed a law allowing cities to license short-term rentals and regulate nuisance properties. The City quickly sprang into action, adopting rules requiring short-term rentals to be licensed and creating Good Neighbor Guides to educate short-term rental property owners and their neighbors about the requirements. The CIty also created a Short-Term Rental Map Tool that allows residents to view the license status and understand the impact of short-term rentals in their neighborhoods. The Map Tool draws on the City’s Data Service Standard – one of the first cities in the United States to publish one – that guides the City in developing reliable and informative data services and products for its residents and businesses.

2019 Silver Certification


Launched an open data portal that provides performance data to collective benchmarking databases, which allows cities to help each other set more informed targets and put their own progress into perspective.


Used predictive analysis to calculate yearly projected water needs, which has allowed the City to continue a 20-plus-year streak of pumping less groundwater out of its aquifers than it puts back in.


Teamed up with the Behavioral Insights Team (BIT) to identify the effectiveness of messages on utility bills through randomized control trials that led to more customers choosing eco-friendly, cost-effective options such as signing up for paperless billing.


Analyzed the effects of altering traffic signals after prior accidents to develop data-based, location-specific plans for minimizing traffic jams after future accidents.

Honoring Scottsdale’s Memory

The skies were clear blue at noon as a crowd cheered the world’s oldest official Pony Express to the end of its 200-mile journey, outside the Museum of the West, in Old Town Scottsdale. This annual delivery of 20,000 pieces of first-class mail is among the special events and other attractions that bring about 9 million visitors and around $41 million in tax revenue to this Southwestern city each year. Old Town, the City’s downtown, still grows olive trees from its first days of settlement in the late 1800s, at the same time that it has become the spring home of the San Francisco Giants and begun to emerge as a center for high-tech businesses. It’s just one manifestation of how Scottsdale, the “West’s Most Western Town,” is a city that remembers its past while steadfastly preparing for the future.

Adopting a Business Mindset in City Hall

Scottsdale stands out for adopting a business mindset to run a well-managed government, embracing transparency so that residents receive the information they deserve, and embedding data in decision-making to ensure the best outcomes. And the efforts are paying off — in conserving water, serving vulnerable residents, minimizing traffic jams, and beyond.

Scottsdale joined What Works Cities in June 2016 and, soon after, codified an open data policy and launched an open data portal. Scottsdale has also deepened its citywide performance management. City Manager Jim Thompson says, “When we look at data and analytics, even though we assumed something was best, when we overlay old data with new or more specific data, we may find a new way to do things.” To continuously evaluate progress is to continuously improve.

The City is publicly reporting on that progress through a public-facing performance management portal, and provides performance data to collective benchmarking databases, an effort that allows cities to help each other set more informed targets and put their own progress into perspective by comparing themselves to other similar municipalities regionally and nationally. Scottsdale has gone on to earn a 2018 Certificate of Excellence in performance management, the highest distinction, from the International City/County Management Association.

If it’s a flaw in a process that’s causing shortcomings in performance, Scottsdale has a solution for that, too: a cross-departmental team that helps colleagues from across City Hall implement process improvements. A recent project involved modernizing the website for reserving facilities like picnic areas or volleyball courts from the Parks & Recreation Department. What was once a landing page with instructions to call a landline transformed into a full-service resource for determining availability and making a booking. Use of the website increased 200 percent in the first month following the redesign. Most importantly, residents are happier, and the ability to provide better customer service is boosting morale among department employees.

Making Every Drop Count

The Scottsdale Water Department Director Brian Biesemeyer was acting City Manager when Scottsdale’s open data work got underway, so it’s no surprise that he’s pointing his team to the numbers to make sure “every drop counts,” as he aptly puts it. As a desert city, Scottsdale understands the value of water to residents and the economy.

Each year, by October 1, the department must submit its water order for the following year — meaning calculations for projected water needs are already underway 14 months out. In 2018, by using predictive analytics, there was a difference of fewer than 100 million gallons (or 0.4%) between planned and actual water use. An inaccurate prediction could have required tapping into underground aquifers — a crucial reserve in this arid city — or paying for water it didn’t use. An accurate water order not only saved money; it allowed the department to continue to recharge local aquifers. In doing so, the City continued a 20-plus-year streak of pumping less groundwater out of its aquifers than it puts back in. Scottsdale was the first city in Arizona to achieve this feat — known as safe yield — and has received the Sustainable Water Utility Management Award, from the Association of Metropolitan Water Agencies, the highest industry recognition for municipal water providers. Accurate data analysis and transparency help drive better planning practices that benefit Scottsdale residents now and over the long term.

Data analysis has also saved the department nearly half a million dollars each year by tracing the need for costly meter replacements in one part of the City to a pH imbalance, now corrected, originating from the water plant serving the affected area.

Gathering BITS of Insight

Scottsdale regularly communicates with residents on everything from issuing water bills to recruiting new employees. When Scottsdale joined What Works Cities, it expressed an interest in identifying which messages resonate best with local residents. Scottsdale city staff teamed up with the Behavioral Insights Team (BIT) to determine the answer by using randomized control trials to test the effectiveness of messaging and keep tweaking them accordingly. Pretty soon, they identified messages on utility bills that led to more customers donating $1 per month to local nonprofits, or signing up for paperless billing, a more eco-friendly, cost-effective option.

After ending technical assistance with BIT, the City created a team of internal consultants — the Behavioral Insights Team Scottsdale, or BITS — to carry the work forward by helping staff in departments across City Hall apply behavioral science to their projects. The department that’s engaged most with BITS has been Human Services; they’ve identified effective messaging to recruit more volunteers for programs focused on assisting vulnerable seniors, including Beat the Heat and Adopt-a-Senior.

Most recently, they’ve focused on Adopt-a-Family, a program that recruits volunteers to provide food and gifts for income-eligible families during the holiday season. Human Services Specialist Sue Oh recalls a 2018 volunteer who received a family’s wish list, which included a request for a boy’s polo, and wanted to find out what style the child wanted.

When Oh reached out on behalf of the volunteer, she learned that the child’s mother had passed away; his grandmother was now caring for him and his siblings. Oh related this to the volunteer, who began to cry and shared that her husband had recently passed away. She said, “I know this is what I’m supposed to do,” Oh recalls, and voiced her plans to volunteer again this holiday season.

By integrating testing into communications, Scottsdale is more effectively and efficiently engaging with its residents.

The Road Ahead

Scottsdale’s Traffic Management Center.

Sometimes the effects of using data are quietly unfolding behind the scenes of what most residents see on a daily basis. Take the City’s Traffic Management Center, where analyzing the effects of altering traffic signals after prior accidents has informed the development of data-based, location-specific plans for minimizing traffic jams after future accidents. Now staff are turning those human-gathered insights into algorithms that will eventually allow machine learning to respond with greater precision.

There’s a lesson here: Getting from point A to point B in the best way possible is a great goal for the road — and a useful metaphor for driving progress effectively — but it always involves planning ahead. As Assistant City Manager Brent Stockwell drives back to City Hall after our visit to the Traffic Management Center, he paraphrases how a former council member once put it: “See those trees planted there? They’re there because someone in the past was thinking about the future.”
