United States of America Population Pyramid 2014
United States of America in 2014
As of 2014, the United States of America counted 323,115,377 inhabitants. A decade earlier, in 2004, the population was 292,786,254; it has grown by 10.4% since. With a median age of 37.3 years, the United States of America had a youth dependency ratio of 29.0 and an old-age dependency ratio of 21.0 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.
