Gentrification in Chicago is not a new phenomenon; many experts would argue that it is a part of the natual life cycle of urban communities. However, the recent development boom in Chicago has affected many traditionally run-down neighborhoods, including the North Kenwood- Oakland neighborhood on Chicago's south side. The gentrification in that particular neighborhood has brought better housing and new businesses and built a strong community, but it also brought out some latent class-consciousness and class differences between the neighborhood's traditional residents and those who were moving in. In this program, Milt explores how gentrification changed this particular neighborhood with Toni Preckwinkle, 4th ward alderman, and Mary Pattillo, professor of sociology and African American studies at Northwestern University and author of the new book Black on the Block: The Politics of Race and Class in the City.
