Answer:
Following World War II, the United States experienced a greatly elevated birth rate, adding on average 4.24 million new babies to the population every year between 1946 and 1964.
This generation of "baby boomers" was the result of a strong postwar economy, in which Americans felt confident they would be able to support a larger number of children. Boomers also influenced the economy as a core marketing demographic for products tied to their age group, from toys to records.
Constituting as much as 40% of the American population, baby boomers have exerted a strong pull on American culture at large, particularly during the social movements of the 1960s.
Today, most boomers are at or near retirement, prompting concerns for how American society will cope with an aging population.
