New Jersey’s 21 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 New Jersey’s 9,290,841 residents live in just 6 of 21 counties, and the five largest hold 43.5% of the total. Census PEP 2023
  • Income tracks poverty. The gap from richest to poorest runs 2.2×, and the 10 highest-income counties average 6.6% in poverty against 12.5% for the 10 lowest. Census SAIPE 2023
  • Mostly small. Half of New Jersey’s counties have fewer than 469,167 residents, and half report a median household income below $96,965 — a few metros lift the statewide totals well above both. Census PEP 2023 · SAIPE 2023
  • Lopsided density. Only 9 of 21 counties are denser than New Jersey’s statewide average of 1,263 people per square mile — the rest are more rural. Census PEP 2023 · TIGER
