Idaho median age stays below U.S. average in 2025

Idaho’s median age remains below the U.S. average in 2025, while household income has increased during the year.

The two measures describe different parts of life in the state. Median age indicates the midpoint of Idaho’s age distribution: half of residents are older and half are younger. Household income measures money received by households. Together, the figures point to a state that remains younger than the country as a whole while household income has moved higher in 2025.

The development does not establish how large the age difference is or how much household income has increased. It also does not identify whether the income change applies equally across Idaho communities or household types.

The measures provide a concise snapshot of Idaho’s population and finances in 2025. Additional figures would be needed to compare individual counties, explain the reasons for the changes or assess how the measures have shifted over time.
