Final answer:
Following World War II, many black Americans experienced life changes with the continuation of the Great Migration, moving from the rural South to Northern and Western cities for better employment and living conditions.
Step-by-step explanation:
One way that life changed for many black Americans following World War II involves the significant demographic shift known as the Great Migration. This era was marked by a large-scale movement of African Americans from the rural South to urban areas in the North and West in search of better job opportunities, higher wages, better schools, and an escape from the racially oppressive Jim Crow laws. The migration continued to shape the social, cultural, and economic landscapes of American cities.
