African-Americans have decided to move to the South in recent years. The 2010 Census was the first one in decades that showed more blacks living in the South than in the North. For most of the 20th century, blacks migrated out of the South en masse, finding new jobs and new lives in places like Detroit, Cleveland and Chicago.
Now, the Great Migration has reversed. In the first decade of the 21st century, 75 percent of African-American population growth occurred south of the Mason-Dixon Line, the highest that number has been in decades. Meanwhile, states such as Michigan and Illinois saw absolute declines in their black populations.
