Idaho population continues strong growth

The U.S. Census estimates Idaho’s July 2023 population at 1,964,726 — an increase of 1.3% from July 2022 — ranking it fourth nationally in percentage growth. Despite ranking 17th in numerical growth and falling from its top-10 status of the past two years, Idaho still outpaces the national population growth rate.

Idaho’s population growth in 2023 was double the national average of 0.5%. The U.S. added 1.6 million people, bringing its population estimate to 334,914,895 — higher than the growth rate of 0.4% in 2022 and 0.2% in 2021.

While most states experienced a population rebound from 2022 to 2023, only eight saw a decline — a contrast to the 18 declining states of 2021-2022.

Breaking down Idaho’s 2023 population growth reveals a shift, with 78% attributed to in-migration, primarily domestic, and 22% from natural change (births minus deaths). International migration increased from 5% in 2022 to 18% in 2023, with a significant increase in natural change.

Despite a slowdown in domestic migration from 2021, Idaho’s estimated increase of 15,389 still places it fourth in percentage change.
