Dakota City, NE (ZIP 68731) sits in Dakota County within the Sioux City metro area. The page draws on 2 federal data feeds retrieved Apr 27. Top health signal: Obesity comes in above the national average at 43.1%. NCES lists 1 schools serving the area, 1 non-charter. 2 colleges and universities serve the area, with median in-state tuition of $6,028. IRS data shows average household income (AGI) of $71,831, well above the ~$45K national average per return. The most recent FEMA disaster declaration here was winter storm-related (SEVERE WINTER STORM AND STRAIGHT-LINE WINDS, 2025). Nebraska levies a graduated state income tax (top rate 5.20%); a household at the local median AGI of $71,831 would pay roughly $2,241/year before deductions. IRS migration data (2022-2023) shows a net loss of 272 residents (124 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 $83,798, fair market rent of $1,290 for a two-bedroom, and a typical home value of $251,011, up 7.6% 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.
