United States of America Population Pyramid 2100
United States of America in 2100
United Nations projections (medium variant) put the population of the United States of America at 421,278,890 in 2100. Ten years before, in 2090, the projected population is 414,457,640 — 1.6% lower.
Half of the population would be younger than 46.3 years, with 14.4% children under 15 and 28.4% aged 65 or older. This is a constrictive pyramid — its base is narrower than its middle, the signature of sustained low birth rates and population ageing.
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.
