Cost of Living in Brookings
Brookings' cost-of-living picture is genuinely favorable and this record discloses it precisely: modestly below-national-average cost-of-living indices and no state income tax sit alongside a real, comparatively elevated property tax rate this record does not omit.

Cost-of-living aggregators reviewed this pass cited Brookings running modestly below the U.S. national average, with indices of approximately 93, 94, and 97 across three separate 2026 sources (where 100 represents the national average) -- one source cited Brookings running approximately 5% below the national average and, more strikingly, approximately 32% below South Dakota's own statewide average.
Housing and Rent Run Genuinely Below the National Median -- a Real, Disclosed Strength
As detailed on the housing-market and renting topic pages, Zillow's cited average home value (~$311,934) and Redfin's cited single-month median (~$315,000) both run roughly 23-25% below the ~$408,776 national comparison figure this project uses consistently. RentCafe's cited average rent across all apartment types ran approximately $1,236/month as of July 2026, up ~10.11% year-over-year.
South Dakota's Real, Genuine Absence of a State Income Tax
As detailed on the taxes topic page, South Dakota levies no state individual income tax -- a real, genuine, substantial cost-of-living advantage for wage earners and retirees alike, per this project's South Dakota manifest research context.
Property Tax Runs Genuinely Above the National Comparison Figure -- an Honest, Unflattering Fact
As detailed on the property-taxes topic page, Brookings County's cited effective property tax rate (~1.13-1.38%) runs above both the ~1.02% national comparison figure and South Dakota's own ~1.07% state average -- a real, disclosed cost this record does not omit even though it runs counter to Brookings' otherwise favorable cost-of-living picture.
A Real, Disclosed Low-Confidence Outlier on One Cost-of-Living Citation
This record discloses a real, disclosed data-quality issue directly: a separate, older City-Data citation (December 2024) put Brookings' cost-of-living index at approximately 74.2 -- a real, disclosed outlier this record treats as likely stale or differently-scoped given its sharp divergence from the more current, more numerous 93-97 range cited by three separate 2026 sources.
Key takeaways
- Cost-of-living aggregators cited Brookings running modestly below the U.S. national average (indices of approximately 93-97 across three 2026 sources).
- Brookings' cited home-value and rent figures run below national comparison figures -- a real, disclosed affordability strength.
- South Dakota levies no state individual income tax, a real, substantial cost-of-living advantage.
- Brookings County's effective property tax rate runs above the national and South Dakota state comparison figures -- a real, disclosed cost this record does not omit.
- A separate, older cost-of-living citation (74.2) diverged sharply from the more current 93-97 range -- this record discloses that gap rather than picking silently.
