“…In poverty, one important survival strategy is to share resources through family and friendship networks (Belle, 1982;Stack, 1974). Because poor families tend to be limited in mobility and have limited access to more distant family and friends, they have few options other than nearby neighbors for resource-sharing (Gerson et al, 1977;Riger & Lavrakas, 1981;Tognoli, 1987;Yancey, 1971;Wellman & Leighton, 1979). Thus, in low-income inner-city communities NSTs may provide an irreplaceable safety net that middle-class or upper-income communities have little need for.…”
