United States of America Population Pyramid 2070
United States of America in 2070
By 2070, the population of the United States of America is expected to reach 398,218,088. That would be 2.4% more than in 2060 (388,918,395). With a projected median age of 44.7 years, the United States of America would have a youth dependency ratio of 25.0 and an old-age dependency ratio of 43.2 per 100 people of working age. 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.
