United States of America in 2025

In 2025, the United States of America had a total population of 347,275,808 people. Over the previous ten years the population grew by 6.5%, up from 326,126,497 in 2015. With a median age of 39.5 years, the United States of America had a youth dependency ratio of 26.5 and an old-age dependency ratio of 28.5 per 100 people of working age. The pyramid is constrictive: cohorts of children are smaller than those of their parents, reflecting low fertility and an ageing population.

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.
