What Are Idaho Migration Numbers in 2025?
New migration data signals that Idaho’s in-move surge is losing momentum in 2025.
Disrupted Inbound Totals
Indicators
United Van Lines reported 57.8% inbound and 42.2% outbound moves. In both the United and Atlas studies, Idaho ranked as a top inbound state in 2025.
Family was the leading inbound motive at 21.6%.
North American Migration Report ranked Idaho first at 71% inbound.
National move volume fell 3% from 2024.
Meridian had nearly 38% out-of-state movers.
Boise was over 20%.
Demographic Pressure Points
Age distribution skewed older.
The 65+ group led at 41%, followed by ages 55–64 at 28.8%.
Realtor.com noted strong net domestic migration.
In-migration was sourced mainly from Washington (25%), California (21%), and Utah (7%).
Idaho’s immigrant share is 132,000 residents, about 7% of the population.
Immigrants make up about 8% of the labor force.
Immigrants were in 10% of households.
Lawful permanent residents totaled 31,000 statewide.
Is Idaho Migration Slowing for 2025–2026?
Inbound rankings remain strong, but Idaho’s migration surge shows deceleration heading into 2025 and the 2026 outlook.
Growth stayed near 1.4 percent to 1.5 percent, down from 3 percent in 2021.
Disruption in growth speed
Net migration supplied 76 percent of 2025 growth, or 22,063 people.
Yet the slower rate reduces urgency seen in the early 2020s.
Economic implications include softer housing demand pressure and steadier construction schedules.
This easing demand can align with a 2026 housing market that is stalling rather than crashing, as rising inventory trends toward more balanced conditions instead of forced selling.
Public services may see less acute crowding in schools, roads, and utilities.
United reported 57.8 percent inbound versus 42.2 percent outbound moves.
2026 outlook stays muted
No official 2026 totals are available, but 2025 patterns point to steady inflows without re-acceleration in key markets.
Idaho still outpaces the 0.5 percent national average, suggesting moderation, not reversal.
Where Are Idaho’s New Residents Moving From?
Where Idaho’s new residents are moving from is increasingly concentrated in a few high outflow states and nearby neighbors.
Coastal sources remain led by California, which accounted for 21% of inbound movers in a Census-linked Realtor.com analysis.
In the Treasure Valley, just 2.7–3.0 months of housing inventory is keeping buyer competition intense.
Neighboring Patterns Tighten
Washington supplied 25% of Idaho’s net domestic migrants in 2025, far outpacing Utah at 7%.
About 90% of Idaho’s 22,063 net migrants came from other U.S. states, leaving international inflows near 10%.
High Outflow States Feed the Stream
North American moving data for 2025 showed California at 60% outbound, with New Jersey at 57% and Illinois at 56%.
Van line studies also flagged New Jersey and pointed to Northeast and Midwest exporters such as Pennsylvania at 55% and New York’s large net outflows.
What’s Driving Idaho Migration: Family, Jobs, Lifestyle?
As the flow of newcomers concentrates in a handful of feeder states, the reasons for moving to Idaho are sharpening into a few dominant drivers.
Family Pressure
Intergenerational ties
Family is the top inbound reason at 21.6 percent.
Older movers dominate, with ages 65+ at 41 percent and ages 55-64 at 28.8 percent, often reflecting intergenerational ties.
Family is also the largest outbound reason, underscoring churn within extended households.
Work and Lifestyle Competition
Amenity clustering
Jobs rank second at 17 percent, aligning with 35-54 year olds at 22 percent combined.
Lifestyle follows at 15.9 percent, linked to amenity clustering and continued inflows from high-outbound states.
- Family reconnection.
- Employment access.
- Outdoor-oriented daily life.
Net migration drove 76 percent of 2025 growth statewide.
How Idaho Migration Shapes 2026 Housing Demand
Although Idaho’s migration surge has cooled, it continues to set a floor for 2026 housing demand in the Treasure Valley and metros.
Ada and Canyon Counties still add about 2,000 residents monthly, and 2025 net inflows ranged from 9,400 to 2,600.
Supply Squeeze Persists
Inventory remains constrained at about three months statewide, with Boise near 1.48 months.
The lock-in effect limits resale listings even as new listings rose 17.1% in early 2025.
Pricing and Rents Stay Uneven
Statewide values hovered near $462,426 in January 2026, while Boise sold prices reached $522,945.
These gaps reinforce price polarization between core neighborhoods and outer markets like Nampa at $434,995.
With 6% of households cost-burdened and mortgage rates near 6.19%, rental pressure is likely to persist through 2026.
Assessment
Idaho’s outsized migration is cooling as 2025 data show smaller net gains and slower in-state moves.
Fewer arrivals from high-cost coastal metros are reducing pressure on starter homes.
Employment growth remains a stabilizer, but higher mortgage rates and affordability limits are restraining relocations.
Family reunification and quality-of-life moves persist, though at a lower volume.
For 2026, housing demand is shifting toward replacement buying and local household formation.
Markets with new-build supply face the sharpest adjustment.
