United States of America in 2026

As of 2026, the United States of America counts an estimated 349,035,494 inhabitants. That is 6.0% more than in 2016, when the population stood at 329,179,426. Half of the population is younger than 39.7 years; 16.9% are children under 15 and 18.8% are 65 or older. 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.
