At the end of World War II, American soldiers returned home triumphant and, with the help of the GI Bill, built homes by the millions on the edges of America's cities. These homes were predominantly capes and ranches, modest in size, but built to house a growing middle-class as the 20th century became the American century. SeaTac's housing was primarily built during this period, from the '40s through the '60s. A full 52.91% of the city's housing hails from this era.
