Why are some neighborhoods characterized by deep social divisions and violence while others thrive? Why do most cities exhibit sharp neighborhood differences in wealth and poverty, often cheek by jowl as captured in Henry Zorbaugh's classic study from the 1920s, The Gold Coast and the Slum? What are the causes and consequences of today’s “Division Street, U.S.A.”?
For much of his career, Professor Sampson has explored what he calls the "enduring neighborhood effect." Much of this research stems from a largescale and still ongoing study, the Project on Human Development in Chicago Neighborhoods (PHDCN).
