LOCAL POPULATION CHANGE AND VARIATIONS IN RACIAL INTEGRATION IN THE UNITED STATES, 2000-2010.

While population growth has been consistently tied to decreasing racial segregation at the metropolitan level in the United States, little work has been done to relate small-scale changes in population size to integration. We address this question through a novel technique that tracks population changes by race and ethnicity for comparable geographies in both 2000 and 2010. Using the Theil Index, we analyze the fifty most populous Metropolitan Statistical Areas in 2010 for changes in multigroup segregation.

Before : Residential Segregation in a Nineteenth-Century Northern City.

Although some scholars treat racial residential segregation in Northern cities as a twentieth-century phenomenon, recent research on New York and Chicago has shown that black-white segregation was already high and rising by 1880. We draw on data from the Philadelphia Social History Project and other new sources to study trends in this city as far back as 1850 and extending to 1900, a time when DuBois had completed his epic study of . Segregation of "free Negroes" in Philadelphia was high even before the Civil War but did not increase as the total and black populations grew through 1900.
