United States of America Population Pyramid 2045
United States of America in 2045
United Nations projections (medium variant) put the population of the United States of America at 376,106,473 in 2045. Ten years before, in 2035, the projected population is 363,284,716 — 3.5% lower. With a projected median age of 42.2 years, the United States of America would have a youth dependency ratio of 26.0 and an old-age dependency ratio of 36.5 per 100 people of working age. 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.
