Renca, Chile

Building a Mental Health Support System for Adolescents

Project Type:
Health and Wellbeing, Community Engagement, Youth Development

At a Glance


Implemented a pilot school mental health program for young people, achieving an 80% reduction in clinical mental health symptoms.


Launched Chile’s first municipal virtual assistant, powered by AI, allowing thousands of residents per month to get answers to basic questions through multiple social media channels.


Kindergarten attendance rates increased from 80.2% in 2023 to 84.3% in 2024 thanks to a universal cash incentive program.


Created a public data observatory where municipal employees, researchers and residents can view maps and visualizations of municipal services, infrastructure and other key data.

In Renca, Chile, as in so many other places around the world, the COVID-19 pandemic had a psychological impact on young people. A 2018 survey revealed that 60% of residents aged 14 to 16 reported having good mental health. By 2022, that figure had dropped to 40%.

Local leaders in Renca responded with new support for teenagers, built using data on existing mental health programs in the city. Combined with input from young people themselves, the initiative, known as Renca Contigo (Renca With You), is making a real difference.

Renca is a municipality of approximately 160,000 inhabitants and one of the many districts that make up the Santiago Metropolitan Region. Even before the pandemic, Renca had already begun to address youth mental health by creating a community center called Rucalaf, where children can attend therapy sessions focused on play, art, cooking, and other activities. In 2021, Renca added the services of 10 psychologists to several community health centers in the area.

These initiatives helped. However, by 2023, data from Renca showed significant gaps in access. Approximately half of young people aged 15 to 19 who likely needed care were not receiving it. Among those with depression or anxiety, most who attended therapy did not continue treatment, dropping out after one or two visits.

Municipal leaders set out to find out why. In focus groups with teenagers, parents, and mental health professionals, several issues emerged; for example, that the therapists in the program were not trained to work with young people. The most frequent observation had to do with proximity. The therapy appointments offered at community health centers were difficult to access.

Renca responded by moving services to where most young people are: at school. A school-based mental health pilot program was implemented, utilizing brief, scientifically validated interventions (by institutions such as the Johns Hopkins Institute) that were culturally adapted. In 2024, 37 students from three high schools received in-person counseling. Services were provided not only by psychologists but also by social workers, nutritionists, and other staff trained to work with children. In the pilot program, the percentage of students who attended more than six sessions increased significantly to 62 percent, compared to 15 percent among students who traveled to external health centers for care. Overall, the pilot program achieved an 80 percent reduction in clinical mental health symptoms.

“We seek the efficient use of resources for our community. Data helps make that vision a reality, demonstrating how we prioritize resource allocation and how we show our community that resources are distributed fairly among the neighborhoods.”

Mayor Claudio Castro

Based on these positive results, the municipal authorities decided to expand the model, investing more than $2 billion and ensuring its implementation in all 14 public and private schools in Renca by 2025, moving towards universal school-based mental health coverage with a preventive, community-based, and evidence-based approach.

From now on, program coordinators are monitoring data through numerous indicators. For example, they are tracking process-related measures (such as how quickly young people referred to the program are seen by a therapist), the quality of care (how many experience significant clinical improvements), and cost-effectiveness (average cost per patient). They hope to use this and other data to improve the efficiency and impact of their programs, so that young people in Renca continue to feel better about themselves.

“For us, it’s very important to be able to measure what we’re doing,” says Patricia Castillo, the municipal director of health. “This will always be a program that is being tested and refined based on our operational methods and the feedback we receive from users.”

Maipú, Chile

Data Transformation and Transparency in Maipú Water Services

Project Type:
Health and Wellbeing, Infrastructure and Utilities, Public Safety

In 2021, Maipú was going through a serious crisis in the drinking water and sewage service: more than 20,000 water leaks flooded its streets that year, affecting the quality of life of more than half a million inhabitants. A neighborhood came to be nicknamed “the Venice of Maipú”, and one resident mentioned that some leaks in her neighborhood had been going on for more than two years.

The Municipal Drinking Water and Sewer Service (SMAPA), the only municipally managed water company in Chile, was struggling with aging infrastructure, inefficiency and limited resources, while public trust in local government was low due to measures taken by the previous administration: bad management and a deficit of $31 billion pesos ($31 million dollars).

In response, since taking office in June 2021, Mayor Tomás Vodanovic has prioritized the management of SMAPA as a cornerstone of his administration’s agenda. It was decided to invest an additional $5 billion ($5 million dollars) for the maintenance of drinking water and sewage networks. However, the key to success was improving tracking and analysis. To save resources, city staff inspected water infrastructure and worked closely with the public safety team. Through mixed patrols between professionals from different areas, the tours were more efficient, since they only needed a mobile phone to travel. They then took this data in the field and created comprehensive dashboards, allowing real-time monitoring and analysis of water and sewer service reports. Today Maipú can better allocate resources and proactively address more problems.

This work was supported by administration support, with a commitment to building a data culture across government. Maipú joined the Digital Transformation Leaders Network, participated in the Bloomberg Philanthropies City Data Alliance, and city leaders are active members of the What Works Cities Certification Community. In each of these networks, Maipú has learned from other cities and has developed a disciplined, consistent and challenging approach to data.

For example, the Urban Advisory Department developed the Maipú Territorial Information System (SITMA), powered by technology with ArcGIS. This platform helps the City optimize resource allocation by breaking down data by neighborhood and provides transparency by allowing residents to monitor projects and report issues.

“We only measure in terms of improving people’s lives. It makes no sense to use graphs, numbers and bars just because of our love of numbers and figures, they must effectively push municipal management to have a greater impact on the people.”

Mayor Tomás Vodanovic

“Teams no longer come with proposals unless they have data. “Hey, I think that’s a good idea” isn’t enough. Now people come with a georeferenced proposal, analyzed or compared with other municipalities. In other words, analysis is already part of the process.”

Transparency and rebuilding public trust have been integral to Maipú’s efforts to improve SMAPA. Management launched a robust communications campaign, using social media, newsletters and community meetings to inform and engage residents. In addition, educational initiatives, such as the Museum of Water, share the history and importance of SMAPA as the only municipal water service in the country.

Maipú’s efforts bore fruit: the City went from 29,000 water leaks in 2021 to less than 2,000 in 2024. Today, Maipú’s innovative approach serves as a model for other cities that want to make their public services reliable for the community. This is a testament to what can be achieved when technology and transparency drive public service.

“The What Works Cities Certification is an important tool for recognition and internal mobilization. It shows that we value the good performance of city workers and is an example for others to follow.”

Las Condes, Chile

Crime Falls as Data-Driven Governance Rises

Project Type:
Infrastructure, Public Safety, Technology, Transportation

At a Glance


More than 3,000 innovative security technologies, including cameras, sensors and drones in Las Condes. Of these, there are about 1,900 video surveillance cameras that stream data to an analytics software that detects possible crimes.


Robberies fell by 22% in 2023.


51 different movements the analytics program flags as potential problems.

Crime rates have risen in recent years in Latin America. But Las Condes, an affluent municipality of about 340,000 people that abuts Chile’s capital city, offers a different story: Its crime levels have fallen. For Las Condes’ leaders, this is proof that their strategy for improving public safety is working as planned.

Las Condes doesn’t have its own police force—instead there are municipal guards that are usually first responders. Municipal guards help uphold local regulations and maintain public order, but have limited law enforcement authority. Thus, state police forces are ultimately responsible for public safety. So leaders turned to technology, not manpower, to help make the city safer. Setting up a municipal network of security cameras around the city was key. To determine the most effective sites for thousands of cameras, the City identified locations with high numbers of thefts and other crimes between 2018 and 2022. The next step was integrating the cameras (there are now about 1,900 in place) with a predictive analytics software platform that could support fast police responses. The software analyzes data from the videos and automatically alerts municipal guards to potential crimes.

While Las Condes’ leaders were confident the security video network would boost safety, they also understood that residents had legitimate privacy concerns. To address them, officials make footage available to residents upon request. They’re also transparent about how the cameras are used—and how they fit into Las Condes’ larger public safety strategy.

The City maintains a heat map detailing crime—e.g., where it happened, what was stolen, mode of transportation, etc. Each week, municipal inspectors review the map, while also tracking a predictive crime model fed by fresh data.

In 2022, crime fell across all categories except one: pedestrian robberies. After digging into the data, including video footage, officials realized there was a surge in crimes committed by people disguised as motorcycle delivery drivers. In response, the City’s public safety inspectors began using motorcycles to improve their mobility and address robbery hotspots. The result: Robberies dropped by 22% in 2023. As of May 2024, crime has dropped by 29% compared to the same period in 2023.
