South Dakota’s 66 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 South Dakota’s 919,318 residents live in just 5 of 66 counties, and the five largest hold 51.1% of the total. Census PEP 2023
  • Income tracks poverty. The gap from richest to poorest runs 3.1×, and the 10 highest-income counties average 7.9% in poverty against 31.0% for the 10 lowest. Census SAIPE 2023
  • Mostly small. Half of South Dakota’s counties have fewer than 5,294 residents, and half report a median household income below $67,180 — a few metros lift the statewide totals well above both. Census PEP 2023 · SAIPE 2023
  • Lopsided density. Only 18 of 66 counties are denser than South Dakota’s statewide average of 12 people per square mile — the rest are more rural. Census PEP 2023 · TIGER
