Median Age in the United States 

Median Age Demographics
Change Location...

Slowly but surely, Americans are getting older. From 2000 to 2018, the U.S. median age rose from 35.3 to 38.2, according to Census data. This report explores how the United States’ population’s age is changing.

The American Community Survey (ACS), conducted by the U.S. Census Bureau, publishes detailed estimates on the United States' 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.

How does the U.S. median age vary by people's place of birth?

Foreign-born people include anyone who is not a U.S. citizen at birth, including immigrants who become naturalized citizens. 

How does the U.S. median age vary based on geographical mobility—when and from where people moved to new homes?

Geographic mobility is the Census' term for Americans' migration patterns—if, when, and from where people moved to new homes. Note that this chart's population does not include infants less than one year old. 

How do workers' median ages vary by their means of transportation? 

Based on ACS data about commuting, this chart only considers the population of workers—and excludes anyone 15 and younger.
