MAP 27.4 Black Voter Registration in the South, 1964 and 1975
After passage of the Voting Rights Act of 1965, black registration in the South increased dramatically. The bars on the map show the number of African Americans registered in 1964, before the act was passed, and in 1975, after it had been in effect for ten years. States in the Deep South, such as Mississippi, Alabama, and Georgia, had the biggest increases.
