United States of America Population Pyramid 2023
United States of America in 2023
The population of the United States of America in 2023 was 343,477,335. That is 7.3% more than in 2013, when the population stood at 320,110,759.
Half of the population was younger than 39.0 years; 17.6% were children under 15 and 17.4% were 65 or older. This is a stationary pyramid — similar numbers in each age group up to the older cohorts, the signature of near-replacement fertility.
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.
