Pennsylvania’s 67 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 Pennsylvania’s 12,961,683 residents live in just 9 of 67 counties, and the five largest hold 37.5% of the total. Census PEP 2023
  • Income tracks poverty. The gap from richest to poorest runs 2.5×, and the 10 highest-income counties average 8.6% in poverty against 16.5% for the 10 lowest. Census SAIPE 2023
  • Mostly small. Half of Pennsylvania’s counties have fewer than 83,094 residents, and half report a median household income below $62,918 — a few metros lift the statewide totals well above both. Census PEP 2023 · SAIPE 2023
  • Lopsided density. Only 19 of 67 counties are denser than Pennsylvania’s statewide average of 290 people per square mile — the rest are more rural. Census PEP 2023 · TIGER
