Wyoming’s 23 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 Wyoming’s 584,057 residents live in just 5 of 23 counties, and the five largest hold 53.0% of the total. Census PEP 2023
- Income tracks poverty. The gap from richest to poorest runs 2.3×, and the 10 highest-income counties average 8.7% in poverty against 12.7% for the 10 lowest. Census SAIPE 2023
- Mostly small. Half of Wyoming’s counties have fewer than 14,334 residents, and half report a median household income below $70,330 — a few metros lift the statewide totals well above both. Census PEP 2023 · SAIPE 2023
- Lopsided density. Only 6 of 23 counties are denser than Wyoming’s statewide average of 6 people per square mile — the rest are more rural. Census PEP 2023 · TIGER
