Montana’s 56 counties, by the numbers

Every county’s population, median household income, unemployment, density, and land area — sortable by any column, so you can find yours or rank by what matters to you. A few patterns run through the data:

  • Concentrated. Half of Montana’s 1,132,812 residents live in just 5 of 56 counties, and the five largest hold 54.5% of the total. Census PEP 2023
  • Income tracks poverty. The gap from richest to poorest runs 1.9×, and the 10 highest-income counties average 9.4% in poverty against 19.2% for the 10 lowest. Census SAIPE 2023
  • Mostly small. Half of Montana’s counties have fewer than 7,753 residents, and half report a median household income below $59,534 — a few metros lift the statewide totals well above both. Census PEP 2023 · SAIPE 2023
  • Lopsided density. Only 11 of 56 counties are denser than Montana’s statewide average of 8 people per square mile — the rest are more rural. Census PEP 2023 · TIGER
