The aim of this study is to assess the relationships between residential satisfaction (RS), sense of community (SOC), and citizen participation in a sample of 740 Spanish adults, and the impact these variables have on their life satisfaction (LS). The results show low levels of participation (social and community) and medium to high levels of LS, SOC, and RS. LS is positively affected by such situations as being in a relationship, being employed, and home ownership. It appears that positive socio-economic conditions favor LS. A regression analysis indicates that 15.2 percent of LS can be predicted by both RS and participation.
