After WWII, many Americans migrated to the newly built suburbs and Sunbelt states. The rise of the suburbs was fueled by the demand for housing and availability of low-interest home loans for veterans. The construction of the interstate highway system and rise of car ownership facilitated suburban expansion. Meanwhile, the U.S. economy transitioned from manufacturing to service-based, more women joined the workforce, and franchise businesses and multinational corporations grew. Higher education also expanded across the country during this period of social and economic transformation in 1950s America.
