A large part of the cause of the Baby Boom was an after effect of World War II where the bombed out cities and fractured economies increased the needs for goods and services in unprecedented peacetime amounts. America cranked up the exports and supplied the "free world" with goods to rebuild its own economies. Furthermore, in the U.S. the G.I. Bill enabled record numbers of individuals to attend college and obtain, perhaps in most cases, the second college degree in their extended families. This led to an increase in education and granted higher incomes to families allowing them the resources to produce more children.
