This paper has 2 purposes: (a) to present the differences in demographic and health characteristics of older women volunteers and nonvolunteers in a community-based sample; (b) to identify the motivations of current and past volunteers, as contrasted with those who have never volunteered. A population-based survey was conducted with a sample of 1,104 women aged 50 to 80 years in the state of Washington. Nonvolunteers were less likely to be married and were slightly less likely to be White than were current or past volunteers. Demographic variables (e. g., age) and health status predicted level of reported motivation for volunteering. These data provide us with population-based estimates of volunteering and motivations for older women.
