Fresh.Data current as of Apr 24, 2026
Little Eagle, SD (ZIP 57639) sits in Corson County. The page draws on 1 federal data feed retrieved Apr 24. Top health signal: Obesity comes in above the national average at 45.3%. No NCES schools are mapped to this ZIP in the current dataset. BLS QCEW reports average annual pay of $48,202 per worker, roughly 26% below the US average. Severe Storm accounts for 50% of the 16 FEMA disaster declarations on record for this ZIP. Annual average temperature is just 43.2°F per NOAA's 1991–2020 Climate Normals — a notably cold-weather climate. County Health Rankings reports 37,698 years of potential life lost per 100,000 (2025) — well above the national county median. 36.1% of residents in this county are flagged low-access by USDA's 2025 Food Environment Atlas — a notable supermarket-access gap. South Dakota has no state income tax (Tax Foundation 2025). IRS migration data (2022-2023) shows a net loss of 133 residents (64 households) — the ZIP's primary county is shrinking. Both healthcare access and on-paper school density skew lighter than national norms; what shows up here is a snapshot, not a verdict — neighborhood-level texture matters at this scale. Notable: median household income $18,125, fair market rent of $950 for a two-bedroom, and a 87.9% poverty rate (well above the ~12% US average). Every figure on this page links to its underlying federal dataset with a retrieval date so you can audit the freshness yourself.

What these numbers say together
Little Eagle, SD (ZIP 57639) sits in Corson County. The page draws on 1 federal data feed retrieved Apr 24. Top health signal: Obesity comes in above the national average at 45.3%. No NCES schools are mapped to this ZIP in the current dataset. BLS QCEW reports average annual pay of $48,202 per worker, roughly 26% below the US average. Severe Storm accounts for 50% of the 16 FEMA disaster declarations on record for this ZIP.

South Dakota has no state income tax (Tax Foundation 2025). IRS migration data (2022-2023) shows a net loss of 133 residents (64 households) — the ZIP's primary county is shrinking. Both healthcare access and on-paper school density skew lighter than national norms; what shows up here is a snapshot, not a verdict — neighborhood-level texture matters at this scale. Notable: median household income $18,125, fair market rent of $950 for a two-bedroom, and a 87.9% poverty rate (well above the ~12% US average). Every figure on this page links to its underlying federal dataset with a retrieval date so you can audit the freshness yourself.
The two domains pull in different directions. Healthcare access reads strong, but the on-paper school count is on the lighter side — that’s less a quality signal and more a density one. Households here often look at districts a few ZIPs over for school choice while keeping their providers local.
- Fair market rent for a two-bedroom ($950/month, HUD SAFMR) represents 63% of median household income ($18,125, Census ACS) — above the 30% affordability threshold commonly used by housing experts.
- Lower median household income ($18,125, Census ACS) sits alongside an above-average 45.3% obesity rate (CDC PLACES) — a pattern that correlates with reduced healthcare access in lower-income areas.
One concrete reading worth keeping: Depression prevalence sits near the national rate at 23.7%. Each figure on this page links to the original federal dataset with its retrieval date — this synthesis is a reading, not a substitute for the underlying records.
