Studies conducted in specifically age-segregated housing for older persons suggest that such age-homogeneous settings encourage networks of friendships and mutual assistance. Since patterns of age segregation exist within communities, such segregation may result in similar social benefits. Interviews (N=1,185) assessing social networks were conducted with persons aged 60 and older. Two measures of neighborhood age structure were used to determine the age segregation of neighborhoods. Results indicated that, although children were preferred for instrumental and expressive supports, neighbors were frequently used for both types of support and were substituted for unavailable children for instrumental help. Whether neighbors were chosen for instrumental or expressive help appeared to contribute little to overall well-being. General involvement in neighborhood networks showed similar patterns. Closest neighbors and neighbors who were confidants tended to be age peers, with age being less important for instrumental or emergency help. Living in an age-segregated neighborhood had little relation to getting instrumental or expressive support from neighbors or to general involvement with neighbors. The results provide little evidence that residential age segregation contributed to overall well-being. (NRB)
