The black butterfly : the harmful politics of race and space in America / Lawrence T. Brown.

"This book discusses the long history of the deleterious effects of racial segregation on health in the United States. Author Brown puts Baltimore under a microscope because Baltimore was the first city in America to enact segregationist legislation and because it remains hypersegregated to this day. "Black butterfly" describes the shape of a demographic map that plots Baltimore's population by race: a white central axis with black wings east and west"-- Provided by publisher.
