Yes, during World War II, the populations of states and cities with military bases and defense industries saw significant increases. The demand for military personnel and workers in factories producing war materials led to a surge in migration to these areas. Cities such as Detroit, Los Angeles, and various locations in the South and West experienced rapid growth as they became hubs for wartime production and military training. This demographic shift was driven by job opportunities and the influx of military personnel and their families.
