Two numbers, two different cities

Almost every argument about Black Atlanta starts with a statistic that is technically true and quietly answers a different question. The city of Atlanta and the Atlanta metro area are not the same population, and a share of one tells you little about the other. The city is dense, historically Black, and bounded. The metro is sprawling, more than five million people, and holds the far larger total number of Black residents.

When someone says Atlanta is a Black-majority city, they are usually describing a period in the city's recent history. That share has moved over the last two decades as the city's overall population grew and changed. The honest answer to "what percentage of Atlanta is Black" is that it depends on the year, the boundary, and whether the count includes people who identify as Black alone or Black in combination with another race.

Why the vintage matters

Census race categories, question wording, and instructions have changed repeatedly since 1790, and respondents can answer differently from one cycle to the next. A figure quoted without its year is not a fact about Atlanta — it is a fact about someone's memory of Atlanta.

This entry tracks the sources rather than publishing a single frozen number, because the number is the least durable part of the story.
