Colstrip, MT (ZIP 59323) sits in Rosebud County. The page draws on 2 federal data feeds retrieved Apr 27. Top health signal: Annual Checkup comes in above the national average at 69.7%. NCES lists 3 schools serving the area, 3 non-charter. 2 colleges and universities serve the area, with median in-state tuition of $5,414. FDIC counts just 1 bank branch in this ZIP (Summary of Deposits, 2024) — residents likely lean on neighboring ZIPs or online banking for most services. Social vulnerability is low in this ZIP at the 20th percentile (CDC SVI), reflecting strong baseline resilience to public-health emergencies and natural disasters. The most recent FEMA disaster declaration here was straight-line winds-related (SEVERE WINTER STORM AND STRAIGHT-LINE WINDS, 2026).

New residents arriving here predominantly come from Yellowstone County, MT (IRS SOI Migration, 2022-2023). Healthcare access is the area's quieter strength; school options sit on the lighter side, so families may find themselves looking at districts a few ZIPs over.

What these numbers say together
Colstrip, MT (ZIP 59323) sits in Rosebud County. The page draws on 2 federal data feeds retrieved Apr 27. Top health signal: Annual Checkup comes in above the national average at 69.7%. NCES lists 3 schools serving the area, 3 non-charter. 2 colleges and universities serve the area, with median in-state tuition of $5,414. FDIC counts just 1 bank branch in this ZIP (Summary of Deposits, 2024) — residents likely lean on neighboring ZIPs or online banking for most services. Social vulnerability is low in this ZIP at the 20th percentile (CDC SVI), reflecting strong baseline resilience to public-health emergencies and natural disasters. The most recent FEMA disaster declaration here was straight-line winds-related (SEVERE WINTER STORM AND STRAIGHT-LINE WINDS, 2026). Median daily AQI is just 4 per EPA AQS (2024), comfortably inside the Good range, with NO₂ as the primary pollutant on most measured days. County Health Rankings reports 24,380 years of potential life lost per 100,000 (2025) — well above the national county median. New residents arriving here predominantly come from Yellowstone County, MT (IRS SOI Migration, 2022-2023). Healthcare access is the area's quieter strength; school options sit on the lighter side, so families may find themselves looking at districts a few ZIPs over. Notable: median household income $87,321, fair market rent of $1,250 for a two-bedroom, and a typical home value of $224,891, down 4.5% over the past year. Every figure on this page links to its underlying federal dataset with a retrieval date so you can audit the freshness yourself.
The two domains pull in different directions. Healthcare access reads strong, but the on-paper school count is on the lighter side — that’s less a quality signal and more a density one. Households here often look at districts a few ZIPs over for school choice while keeping their providers local.
One concrete reading worth keeping: Depression prevalence sits near the national rate at 23.8%. Each figure on this page links to the original federal dataset with its retrieval date — this synthesis is a reading, not a substitute for the underlying records.
