What the figure measures
Tabulation of current state of residence crossed by state of residence 1 year ago. This is a 1-year mobility / previous-residence statistic, not a count of household-goods shipments.
Universe: population 1 year and over. Dataset: State-to-State Migration Flows: 2024 American Community Survey 1-Year Estimates (Table T13). Official release: Jan 21, 2026. Last checked: Sep 7, 2026. Status: LATEST AVAILABLE. Margins of error in these tables are Census Bureau 90% margins of error.

Difference ± 2,452
Long-haul (750–1,500 centroid miles)
Arizona is the 2nd largest of 45 outbound destinations recorded for Montana — 12.1% of the 35,447 people who left Montana for another state.
Montana is the 20th largest of 49 inbound origins recorded for Arizona — 1.8% of the 234,926 people who arrived in Arizona from another state.
Nationally, this is the 426th largest of 2,096 state-to-state flows that carry an estimate, a margin of error, and a reverse estimate in the 2024 table.
The 90% margin of error is 50.2% of the estimate: the Census interval runs from 2,142 to 6,466. Treat any single-year comparison inside that band as noise.
Montana → Arizona exceeds Arizona → Montana by 1,974 (1.85× the other direction), but that difference sits inside its own 90% margin of error (± 2,452). At 90% confidence the table does not establish a net direction for this pair.
Montana and Arizona do not share a land border. 889 state-centroid straight-line miles; IMMERVEIL planning band: Long-haul (750–1,500 centroid miles). Not driving miles.
Derivations: ranks are competition ranks among cells that carry an estimate (ties share a rank); shares divide the pair estimate by the state’s ACS total; the difference test uses √(MOE₁² + MOE₂²) per Census Bureau statistical-testing guidance; the distance band is an IMMERVEIL planning label on centroid miles, not a tariff zone. Corridor context module v1.0.
Distance note
889 miles is the state-centroid straight-line distance between TIGER-derived geographic centroids of Montana and Arizona. It is not driving mileage, not a highway recommendation, and not a shipping zone. Driving or route miles require a city-to-city pair and a licensed routing provider — this page does not invent that figure. State centroids are computed with d3.geoCentroid on TIGER-derived polygons. Distances shown on state-to-state pages are state-centroid straight-line distances. They are not driving miles, not a highway recommendation, and not a shipping zone. Driving distance requires a city pair and a routing provider.
Planning checklist
- Confirm whether the shipment is interstate (subject to federal household-goods rules) or intrastate.
- Look up the mover’s USDOT before paying a deposit. Open Mover Check.
- Read the estimate type. Open Quote Check.
- Storage between pickup and delivery is common on long corridors — treat unit size as a range. Storage calculator.

This pair is rendered for utility but is noindex until the ACS estimate, reverse flow, centroid distance, and relative margin of error pass the publication gate. Below index threshold (estimate ≥ 5000 and 90% MOE ≤ 50% of estimate). Page still renders.
Questions this page answers
- How many people moved from Montana to Arizona according to the Census?
- The latest official figure is the ACS 2024 1-year estimate of people living in Arizona whose residence one year earlier was Montana: 4,304 ± 2,162 (90% margin of error). It is a previous-residence statistic, not a count of household-goods shipments, trucks, or permanent relocations.
- Do more people move from Montana to Arizona, or the other way?
- Montana to Arizona is nominally larger (4,304 versus 2,330), but the difference of 1,974 is inside its own 90% margin of error (± 2,452). The table does not establish a net direction for this pair.
- How important is Arizona as a destination for people leaving Montana?
- In ACS 2024, Arizona ranks 2nd of 45 recorded destinations for people whose residence one year earlier was Montana, taking 12.1% of that state's out-of-state movers. Ranks are competition ranks among cells with an estimate; ties share a rank.
- Is the Montana–Arizona mileage on this page a driving distance?
- No. 889 miles is the state-centroid straight-line (great-circle) distance between TIGER-derived geographic centroids. It is not driving miles, not a highway recommendation, and not a shipping zone.
- Is 2024 still the latest official state-to-state migration table?
- Yes. The Census Bureau released 2024 State-to-State Migration Flows on 2026-01-21. No 2025 ACS state-to-state table is published. Calendar year is not the dataset year.
- How should I check a mover for a Montana to Arizona shipment?
- Use the USDOT printed on the written estimate. Look the number up in Mover Check (live FMCSA MCMIS census) and confirm the record on FMCSA SAFER before paying a deposit. IMMERVEIL does not rank, score, or endorse carriers.
- How much does it cost to move from Montana to Arizona?
- IMMERVEIL does not invent a mover price, fuel, or toll bracket. ACS Table T13 and the FMCSA census do not contain those figures. Quote Check performs arithmetic on the amount printed on your estimate — including the 110% collect-on-delivery figure for a qualifying interstate non-binding estimate.
