Summary

United States of America in 2011

With a median age of 37.0 years, the United States of America had a youth dependency ratio of 29.1 and an old-age dependency ratio of 19.4 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.
