RUCAS - Chile

Measuring the impact on well-being and health of dwelling and environmental regeneration in Chile

Social housing and health in urban Chile

In the 1980s, Chile faced a housing crisis that resulted in the construction of large numbers of social housing units for low-income community members. Over time, this housing was revealed to be unable to meet basic and minimum habitability standards. Vulnerable populations in some of the largest cities of the country such as Santiago and Viña del Mar live in these units, where they experience overcrowding, exposure to high levels of humidity and mold, deteriorated sanitary and electrical utilities, lack of noise insulation, lack of sidewalks and access to green space, as well as poor road quality. Additionally, the villas are located in the city’s suburbs with poor access to the city center, limited public transport, weakened communities, and serious problems of crime and drug trafficking.

To address these problems (i.e., the qualitative housing deficit), the Chilean Ministry of Housing and Urban Planning (MINVU) launched the Regeneration of Housing Complexes Program (Programa de Regeneración de Conjuntos Habitacionales) to rejuvenate dwellings and neighborhoods.

MINVU is upgrading existing housing units, constructing new units, and transforming neighborhood environments by installing green spaces, building recreation facilities, repaving streets and sidewalks, and installing new bus stops.

Chilean neighborhood 


A team of researchers from the Pontifical Catholic University of Chile is working with local partners to evaluate the impacts of this program on general health, respiratory conditions, mental health, and quality of life. This project is known by the name "RUCAS," an acronym for "Urban Regeneration, Quality of Life and Health" (Regeneración Urbana, Calidad de Vida y Salud).

The study is taking place in Brisas del Mar and Nuevo Horizonte II located in the metropolitan area of Viña del Mar, Chile, as well as in the Marta Brunet community within the Santiago Metropolitan area. Both communities were constructed in the 1990s.

Researchers are conducting household surveys, observing changes taking place within the home environment, measuring temperature and humidity levels within homes, conducting semi-structured interviews and focus groups, and documenting the use of recreational areas. These observations are repeated multiple times in each of the two neighborhoods over the course of the study, both before and after interventions are completed. As of early 2020, data has been collected from more than 2,500 individuals living in nearly 1,000 homes in these communities.

The data will be analyzed to determine the impact of the housing and neighborhood interventions. The evidence produced by this study will be disseminated to policy makers so that they can better understand ways to maximize the positive impacts of similar interventions in the future.

Partnerships and Collaborators

The RUCAS study team works in close collaboration with the Chilean Ministry of Housing and Urban Planning (MINVU) and community leaders in the two communities participating in the study. Over the course of the project, research team members have given more than 20 presentations to community leaders, MINVU representatives and other researchers. These meetings have provided invaluable moments of reflection and feedback to ensure that the study is implemented appropriately both to produce high quality evidence and to maintain a high level of relevance to community members and policymakers.
