Arizona’s 15 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 Arizona’s 7,431,344 residents live in just 1 of 15 counties, and the five largest hold 88.9% of the total. Census PEP 2023
  • Income tracks poverty. The gap from richest to poorest runs 2.0×, and the 7 highest-income counties average 13.5% in poverty against 20.6% for the 7 lowest. Census SAIPE 2023
  • Mostly small. Half of Arizona’s counties have fewer than 124,640 residents, and half report a median household income below $61,225 — a few metros lift the statewide totals well above both. Census PEP 2023 · SAIPE 2023
  • Lopsided density. Only 3 of 15 counties are denser than Arizona’s statewide average of 65 people per square mile — the rest are more rural. Census PEP 2023 · TIGER
