Washington’s 39 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 Washington’s 7,812,880 residents live in just 3 of 39 counties, and the five largest hold 65.5% of the total. Census PEP 2023
  • Income tracks poverty. The gap from richest to poorest runs 2.1×, and the 10 highest-income counties average 9.2% in poverty against 15.9% for the 10 lowest. Census SAIPE 2023
  • Mostly small. Half of Washington’s counties have fewer than 68,389 residents, and half report a median household income below $71,374 — a few metros lift the statewide totals well above both. Census PEP 2023 · SAIPE 2023
  • Lopsided density. Only 9 of 39 counties are denser than Washington’s statewide average of 118 people per square mile — the rest are more rural. Census PEP 2023 · TIGER
