During the Great Migration, around 40% of America's Black population left Southern states to go north or west between 1915 and 1970, and the effects of that exodus continue to reverberate.

While the biggest changes took place decades ago, data shows that America’s Black population has continued to move again. These days, however, census findings from the past 40 years indicate a new pattern of Black migration back to the South and away from cities. America simply looks different than it did a century ago, and this new phase of migration is characterized by very different motivations than the last.
