The post–World War II economic expansion, also known as the postwar economic boom or the Golden Age of Capitalism, was a broad period of worldwide economic expansion beginning with the aftermath of World War II and ending with the 1973–1975 recession. The United States, the Soviet Union and Western European and East Asian countries in particular experienced unusually high and sustained growth, together with full employment.
In the United States and several other nations, the post–World War II boom led to major suburban development and urban sprawl, aided by increasing automobile ownership and cheap oil, as shown in this suburban development in Colorado Springs, Colorado in March 2008.
