Langford, SD (ZIP 57454) sits in Marshall County. The page draws on 2 federal data feeds retrieved Apr 27. Top health signal: High Blood Pressure comes in above the national average at 37.6%. NCES lists 3 schools serving the area, 3 non-charter. 1 college or university serves the area, with median in-state tuition of $8,845. IRS data shows average household income (AGI) of $83,492, well above the ~$45K national average per return. Local establishments report average pay of $31,690 per worker (Census ZBP) — below the US average. BLS LAUS reports county unemployment of just 1.9% (2024), well below the ~4.0% US average and consistent with a tight local labor market. FDIC counts just 1 bank branch in this ZIP (Summary of Deposits, 2024) — residents likely lean on neighboring ZIPs or online banking for most services. FEMA has issued 25 federal disaster declarations affecting this ZIP since 1976 — a high-frequency exposure profile. Annual average temperature is just 42.3°F per NOAA's 1991–2020 Climate Normals — a notably cold-weather climate. Per USDA's Food Environment Atlas, 50.7% of residents in this county live more than 1 mile (urban) or 10 miles (rural) from the nearest supermarket — a deep food-access gap. South Dakota has no state income tax, saving the local median household (AGI $83,492) approximately $3,841/year vs the US average effective state tax rate. IRS migration data (2022-2023) shows a net loss of 71 residents (51 households) — the ZIP's primary county is shrinking. Healthcare access is the area's quieter strength; school options sit on the lighter side, so families may find themselves looking at districts a few ZIPs over. Notable: median household income $69,000, fair market rent of $930 for a two-bedroom, and a typical home value of $206,901, up 8.9% over the past year. Every figure on this page links to its underlying federal dataset with a retrieval date so you can audit the freshness yourself.
