The non-Hispanic Black population grew 6%, slower than the population growth of other groups like Hispanic Americans, up 23% since 2010, and Asian Americans, up 36%. While the overall growth in Black population lagged compared to some groups, it did change in key ways at the local level. Many of the largest centers of Black population shrunk over those ten years. At the same time, some of the fastest-growing counties in the US saw their share of Black population increase.
Six of the 10 counties with the largest Black populations in 2010 lost Black population in 2020
Counties with the highest Black populations in 2010 saw those populations shrink in 2020. For example, Cook County, home to Chicago, has the largest Black population in the US. From 2010 to 2020, its Black population decreased by 80,000 or 6% of its Black residents. Its overall population increased by 1.6%.
