Idaho keeps doing the thing that has defined its economy for a decade: it grows. The pace in 2025 again put it near the top of the national rankings, and the engine is people moving in.
Growth, led by migration
Idaho's population rose about 1.4% over the year in 2025, the second-fastest rate in the nation, pushing the state past roughly 2 million residents. Migration did most of the work: net migration accounted for about 76% of the year's growth — roughly 22,000 people — and about 90% of those movers came from other U.S. states, according to the Idaho Department of Labor. With births declining, in-migration is now the growth story almost by itself.
Where the people are landing
Growth is concentrating in the metros. Idaho's six metropolitan areas accounted for about 92% of statewide population growth in 2025, adding more than 26,000 residents between them. The Boise metro grew about 2.2% — among the fastest large-metro growth rates in the country and the second-fastest in the West behind St. George, Utah.
A tight but loosening labor market
The job market remains tight by historical standards. Idaho's unemployment rate sat around 3.7% while the labor force expanded from roughly 975,700 to 993,400 over the year. The mild uptick suggests hiring is lagging slightly behind a fast-growing labor pool — a healthier problem than the reverse, but one worth watching.
The business read
For Idaho businesses, the outlook cuts two ways. A steady inflow of working-age residents expands the customer base and eases some labor shortages, but it also keeps pressure on housing, infrastructure, and public services — the constraints that could slow the very growth fueling the economy. The companies positioned to win are the ones building for a state that is bigger every year.
