However, this era also brought significant anxieties — particularly the fear of communism during the Cold War. This lesson covers the economic boom of the late 1940s and 1950s, the growth of suburbia, McCarthyism, and the social tensions that lay beneath the surface of American prosperity.

The Post-War Economic Boom

The American economy surged after 1945. Several factors drove this growth.

Consumer demand	Pent-up demand for cars, appliances, and housing fuelled rapid growth
Baby boom	The birth rate surged, creating demand for housing, schools, and consumer goods
Technological innovation	Wartime technology was adapted for consumer use (plastics, electronics, aviation)
Military spending	The Cold War and Korean War kept defence spending high, stimulating industry
