Washington County Median Age Statistics
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.
For locations with populations under 60,000, the ACS is only available in 5-year estimates, rather than single-year periods. The 5-year estimates provide greater geographical granularity but a less granular time period.
