Resident involvement in voluntary organizations within neighborhoods is often predicted by social factors, awareness of neighborhood problems, and past involvement in activism. Less is known about what predicts involvement in gentrifying neighborhoods with a concentration of generational Latino/Latina families. The mixed methods surveys of residents ( n = 195) and in-depth interviews of neighborhood association participants and leaders in the Menlo Park neighborhood of Tucson, Arizona ( n = 17), determined that residents were involved in the neighborhood association this year when they were also involved in other voluntary organizations in the last year and activism since moving into the neighborhood. Latino/Latina households were more involved in faith/religious and school-focused organizations. Caucasian households were more involved in the neighborhood farmer’s market, business or civic groups, arts, and other social change efforts. Therefore, planners and organizers may need to reach out to varying demographics via different organizations where they belong and participate.
