State Overview

Idaho's economy in 2025 and 2026 is marked by continued population growth and a stabilizing, yet competitive, housing market. The state led the nation in inbound migration in 2025, attracting residents seeking affordability and a family-friendly environment, particularly in mid-sized cities. This influx contributes to ongoing demand for housing, even as new construction aims to increase supply.

Major employers like St. Luke's Health System and Micron Technology continue to drive job growth, especially in the Treasure Valley. However, housing affordability remains a primary concern for Idahoans, with recent state legislation passed to encourage smaller, higher-density homes and accessory dwelling units to address the supply shortage. Infrastructure projects are also underway to support the growing population and improve transportation corridors across the state.

Idaho housing policy shifts to boost supply

Driving economic expansion

Micron Technology in Boise is expanding, adding over 17,000 direct and indirect jobs to serve AI demand. St. Luke's Health System, Idaho's largest employer, also continues to anchor job growth across the Treasure Valley. The state's economy is projected to grow by 2.9% from 2025 to 2026.

Current housing market

Idaho's housing market is stabilizing in 2026 with projected price appreciation of 3-5%. Boise experienced a seasonal dip in median home prices in December 2025, but inventory remains tight, with prices expected to climb in spring 2026. Housing affordability remains a top concern for Idaho residents.

Migration patterns

Idaho recorded the most inbound migration in 2025 for the second consecutive year, with many movers coming from Washington, California, and Utah. People are relocating to mid-sized cities within Idaho, seeking family-friendly environments and affordability.

Economic headwinds

While wage growth is steady and unemployment is low, consumers express wariness, and strained households are increasing credit-card debt. Over 800 Idaho workers faced mass layoffs in 2025, with Exyte U.S., Inc. leading with 201 cuts.
