United States of America Population Pyramid 2016
United States of America in 2016
In 2016, the United States of America had a total population of 329,179,426 people. Over the previous ten years the population grew by 10.2%, up from 298,730,210 in 2006. With a median age of 37.6 years, the United States of America had a youth dependency ratio of 28.8 and an old-age dependency ratio of 22.0 per 100 people of working age. The pyramid is stationary: cohort sizes are roughly even through the younger ages, reflecting fertility close to replacement level and slow population change.
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.
