Tenant-based rental assistance has received much attention as a tool to ameliorate American poverty and income segregation. We examined whether a tenant-based voucher program improves long-term exposure to neighborhood opportunity overall and across multiple domains-social/economic, educational, and health/environmental-among low-income families with children. We used data from the Moving to Opportunity (MTO) experiment (1994-2010) with a 10- to 15-year follow-up period and used an innovative and multidimensional measure of neighborhood opportunities for children. Compared with controls in public housing, MTO voucher recipients experienced improvement in neighborhood opportunity overall and across domains during the entire study period, with a larger treatment effect for families in the MTO voucher group who received supplementary housing counseling, than the Section 8 voucher group. Our results also suggests that effects of housing vouchers on neighborhood opportunity may not be uniform across subgroups. Results from model-based recursive partitioning for neighborhood opportunity identified several potential effect modifiers for housing vouchers, including study sites, health and developmental problems of household members, and having vehicle access.
