Housing Choice Vouchers sharply reduce homelessness and other hardships, lift more than a million people out of poverty, and give families an opportunity to move to safer, less poor neighborhoods. These effects, in turn, are closely linked to educational, developmental, and health benefits that can improve children’s long-term life chances and reduce costs in other public programs. This analysis reviews research findings on vouchers’ impact on families with children, people with disabilities, and other poor and vulnerable households.
