Montana’s 56 counties, by the numbers

The table lists every county’s population, median household income, unemployment, density, and land area. Sort it by any column to find yours or rank them. A few patterns stand out:

  • Concentrated. Half of Montana’s 1,144,694 residents live in just 5 of 56 counties, and the 5 largest hold 54.6% of the total. calculated from Census PEP V2025
  • Income tracks poverty. The gap from richest to poorest runs 2.1×, and the 10 highest-income counties average 8.3% in poverty against 17.9% for the 10 lowest. calculated from Census SAIPE 2024
  • The median county. Half of Montana’s counties have fewer than 7,819 residents, and half report a median household income below $63,723. calculated from Census PEP V2025 · Census SAIPE 2024
  • Lopsided density. Only 11 of 56 counties are denser than Montana’s statewide average of 8 people per square mile. calculated from Census PEP V2025 · Census TIGER 2026

Click a column heading to sort all 56 counties. A suppressed estimate (coefficient of variation ≥ 0.30) shows a marker, never a guess. County seats are from Wikidata (CC0), each validated to a Census place inside its county. Where Wikidata has none, the seat comes from the page cited for that county in the seat file, and where the table names no seat, it says why. See the methodology.

The table shows the 50 most populous. Search the map above for the other 77.

A city can reach into more than one county. The table names the one its center falls in; “+N more” counts the others, from the Census Bureau’s count of each city by county part Census ACS 2020–2024 place parts. A row marked (balance) is the Census Bureau’s “balance” of a consolidated city: its population leaves out the separately incorporated places inside the consolidated city (methodology).
