Median Age by State

The typical age of the United States population varies between states. To determine the median age in each state, the U.S. Census Bureau conducts the American Community Survey (ACS), an annual survey of millions of Americans about social, economic, and demographic attributes in all 50 states and the District of Columbia. The purpose of the survey is to help local officials, community leaders, and businesses understand better understand their communities.

The average age in the United States is 38.5 years old. This is a small increase from 38.2 in 2018. States in the western half of the United States tend to have a lower median age than states in the eastern half. The median age ranges from 31.2 years to 45.1 years.

A couple of factors can explain the small increase in the country's median age. The first is that as life expectancy increases and people live longer, the median age will rise. Additionally, birth rates are the lowest they have been in decades. As fewer babies are being born, there are fewer young people to pull the median age down.
