This article explores the relationship between gentrification and racial segregation in Brooklyn, New York with an emphasis on Black Brooklyn. With more than 2.6 million residents, if Brooklyn was a city, it would be the fourth largest in the USA. Brooklyn is the home of approximately 788,000 Blacks with almost 692,000 of them living in an area that historian Harold X. Connolly has called Black Brooklyn. In recent decades, large portions of Brooklyn, including parts of Black Brooklyn have been gentrifying with sizable numbers of whites moving to traditionally Black neighborhoods. One would anticipate racial segregation to be declining in Brooklyn and especially in the areas that are gentrifying. However, this expectation of racial desegregation appears to be false. While there are declines in indices of racial segregation, these declines are frequently marginal, especially when the increase in the number of whites in Black neighborhoods is taken into consideration. At the same time, gentrification has contributed to the displacement or replacement of thousands of long-term African American residents from their homes. This persistence of racial segregation in a time of gentrification raises many questions about the two processes and the effects that they have on African Americans.
