Racial segregation in American cities is no accident. Building on research from her award-winning book, Segregation by Design, political scientist Jessica Trounstine of UC Merced examines how local land use regulations aimed at protecting the property values of white homeowners have generated segregation across racial and class lines that persists today—and how that segregation brings serious inequities in access to quality schools and public amenities. But just as segregation resulted from policy choices, Trounstine shows how desegregation can be a purposeful choice, too, with the right regulatory decisions.
