Since 2000, the number of people living in high poverty neighborhoods has nearly doubled, with people of color disproportionately affected. This new issue brief from the Century Foundation documents the growing trend of concentrated poverty and argues that this re-concentration is not an accident, rather a result of exclusionary zoning practices and new suburban development that fails to include affordable housing. To reduce spatial inequality, the author calls on governments at all levels to end these policies and “work to change the development paradigm that creates high-poverty neighborhoods.”
