Wyoming’s 23 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:

  • Income tracks poverty. The gap from richest to poorest runs 2.5×, and the 10 highest-income counties average 8.2% in poverty against 12.6% for the 10 lowest. calculated from Census SAIPE 2024
  • The median county. Half of Wyoming’s counties have fewer than 14,013 residents, and half report a median household income below $75,757. calculated from Census PEP V2025 · Census SAIPE 2024

Click a column heading to sort all 23 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.
