The central concern of this article is the differences in participation patterns between mobile-home and single-family dwellers residing in contiguous suburban areas. Based on a random sample of60mobile-home and55single-family dwellers, our findings indicate that when sociodemographic characteristics are controlled, mobile-home residents participate more in some forms of informal activities and less in voluntary associations. Type of residence appears to have a greater impact upon associational participation than do sociodemographic characteristics, indicating the need to consider this variable when examining participation patterns.
