United States of America Population Pyramid 1972
United States of America in 1972
The population of the United States of America in 1972 was 212,842,572. Over the previous ten years the population grew by 14.0%, up from 186,724,273 in 1962.
The median age was 28.0 years, and for every 100 people of working age (15–64) there were 43.6 children under 15 and 15.8 people aged 65 or over. The near-vertical sides of the pyramid indicate a stationary age structure, with births roughly balancing the passage of cohorts into older age.
The bulge of cohorts born between 1946 and 1964 — the post-war baby boom — is the defining feature of the United States pyramid, visible as it moves up the age scale over the decades.
