In the context of a rapidly aging population, Costa Rica is fast-tracking the development of public policies that promote healthy aging. With support from PASB, an increasing number of Costa Rican municipalities have signed up to participate in the Global Network for Age-friendly Cities and Communities. At the end of 2023, there were 29 municipalities participating in this network. Intersectoral actions were developed and planned at the community level, geared toward the social determinants of health that affect not only ill-health but also well-being.
