How did U.S. population distribution change between the time of the Civil War and the 1920s?

Between the Civil War and the 1920s, the U.S. population distribution shifted significantly from a predominantly rural society to a more urbanized one. The industrial revolution spurred urban growth as people migrated to cities for job opportunities, leading to a dramatic increase in urban populations. Additionally, the Great Migration saw many African Americans moving from the rural South to northern cities, further contributing to urbanization. By the 1920s, for the first time in U.S. history, more people lived in urban areas than in rural ones.
