This report presents findings of a study by Abt Associates, the NYU Furman Center for Real Estate and Urban Policy, and partners in New York City neighborhoods (referred to as the Abt team) on how the socioeconomic makeup of and change in neighborhoods surrounding New York City Housing Authority (NYCHA) developments affect residents of those developments. The authors also explore some policies and programs that could help residents take greater advantage of changes and opportunities in their surrounding neighborhoods.
