United States of America Population Pyramid 2036
United States of America in 2036
By 2036, the population of the United States of America is expected to reach 364,731,660. That would be 4.5% more than in 2026 (349,035,494).
With a projected median age of 41.5 years, the United States of America would have a youth dependency ratio of 25.5 and an old-age dependency ratio of 34.8 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.
