The postwar economic boom of the 1950s saw unprecedented economic growth and suburban expansion in the United States. Returning WWII veterans utilized the GI Bill to obtain low-cost mortgages, fueling a housing construction boom and the rise of sprawling suburbs. Easy credit, a growing interstate highway system, and affordable cars allowed most Americans to achieve the postwar dream of home ownership. This period also saw a massive baby boom as birth rates surged and families grew in size. New household appliances, a growing consumer culture, and the rise of television all contributed to unprecedented prosperity and economic optimism in 1950s America.
