Which US migration trend began soon after World War II?

Answer:- The correct answer is ‘moving to the suburbs.’ After World War II, there was a mass migration to the Sun Belt, which is the southern and southwestern region of the United States. This migration was caused by a number of factors, including the growth of the defense industry in the Sun Belt, the availability of jobs in the region, and the warm climate. The Sun Belt also became a popular destination for retirees.
