Median Age Demographics
Change Location...

Slowly but surely, Americans are getting older. From 2000 to 2017, the U.S. median age rose from 35.3 to 38.1, according to Census data

The American Community Survey (ACS), conducted by the U.S. Census Bureau, publishes detailed estimates on median age each year, broken down further by demographics and other characteristics. Unlike the Census—which is an exact count of people and households every ten years—ACS statistics are estimated based on a representative survey sample.
