From a peak of population in 1910, the county had declined through 1990. In the early part of the 20th century, particularly from 1910 to 1930, and from 1940 to 1970, it was affected by the Great Migration of blacks out of the segregated society for jobs and opportunities in Midwest and later, West Coast cities. From 1910 to 1920, the population declined more than 17%, as may be seen from the Census table at right. Particularly in the early 20th century, Blacks left to escape the oppression and violence associated with Jim Crow, lynchings, and their disenfranchisement after 1890.
