In this study we examine the impact of parent status and marital status on (1) the foundations of social support networks and (2) who one turns to if help is required with activities of daily living. Data are taken from structured interviews with 678 community-dwelling persons aged 55 and over in London, Canada. This sample overrepresents the childless, single (never married), and divorced, thus ensuring adequate numbers in each category for data analysis. Our findings indicate that marital status is more influential than parent status regarding differences in the foundations of social support. However, for more specific forms of assistance, the divorced and single are more likely than the married, and the childless are more likely than parents to rely on formal support and paid help and less likely to rely on family. As well, for both marital and parent status, there are significant interactions with gender.
