This document summarizes research on "Villages", which are membership-based community organizations that help older adults age in place. It finds that Villages provide services, build social support networks, and promote member empowerment. A survey of Villages found they predominantly serve white, female, homeowners living alone. Preliminary research on one Village program found it helped members feel less isolated and improve access to services. However, ensuring long-term sustainability, inclusiveness, and effectiveness remains a challenge for Villages. The author conducts further research to evaluate Villages and identify factors for success.
