The effect of community social capital externalities on individual mortality risk in Sweden was analyzed. The study was based on a random sample from the adult Swedish population of approximately 95,000 individuals who were followed up for 4-21 years. Registered election participation rate & registered crime rate were used as proxies for community social capital. Both proxies were associated with individual risk from all-cause mortality for males older than 65 years but not for females. A high election participation rate may have exerted protective associations for cardiovascular mortality & deaths due to suicide or other external causes. Similar associations were observed for the crime rate variable. (74 refs.)
