United States of America in 1979

In 1979, the United States of America had a total population of 227,575,084 people. A decade earlier, in 1969, the population was 205,300,032; it has grown by 10.8% since. Half of the population was younger than 29.9 years; 22.8% were children under 15 and 10.9% were 65 or older. The narrow base of the pyramid marks a constrictive age structure: fertility below replacement level and a rising share of older people.

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.
