Abstract: Although social scientists have long examined marital homogamy, most have focused on Western settings, and few have examined a marriage behavior that is relevant for South Asian settings: intercaste marriage. Using survey data from over 3200 individuals in the Chitwan Valley of Nepal, I examine individual and neighborhood influences on intercaste marriage. The findings suggest that an individual`s education is negatively associated with intercaste marriage. Childhood exposure to neighborhood nonfamily organizations such as schools, health clinics, markets, and cinemas, however, is positively associated with intercaste marriage. These neighborhood influences suggest the importance of a life course approach in which early childhood experiences have long-term effects on individuals` intergroup relations, including intercaste marriage.
