Boone County Median Age Statistics
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 Boone County’s population’s age is changing—and how the data compares to the United States as a whole.
The American Community Survey (ACS), conducted by the U.S. Census Bureau, publishes detailed estimates on Boone County's 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.
This report uses ACS 5-year estimates, rather than single-year periods. The 5-year estimates provide greater geographical granularity but a less granular time period.
