Yalobusha County's population peaked in 1910, with the census showing a population of 21,519. By 1920, the population had fallen to 18,738. Effects of the boll weevil and changes in mechanized agriculture reduced the number of workers needed. In this period, many African Americans moved north to industrial cities in the Great Migration, to leave the violence and Jim Crow rules of the segregated South. The population continued to decline steadily for the next 50 years.
