About this ranking

People who are not Hispanic or Latino and report Black or African American as their only race, as a percentage of the total population. United States: American Community Survey five-year estimate, where the period shown is the last year of the five-year span.

US federal statistics ask about Hispanic origin and race separately, and Hispanic or Latino people can be of any race. The shares for White, Black and Asian count people who are not Hispanic and report that race alone, so the published shares do not add up to 100 (people of two or more races and other races are not shown). EU and Spanish statistics do not collect race.

Every value in the ranking comes from the same publisher and the same period, so the cities are compared on one definition. Equal values share a rank.
