Fresh.Data current as of Apr 24, 2026
Sioux City, IA (ZIP 51111) sits in Woodbury County within the Sioux City metro area. The page draws on 1 federal data feed retrieved Apr 24. Top health signal: Obesity comes in above the national average at 41.1%. No NCES schools are mapped to this ZIP in the current dataset. 5 colleges and universities serve the area, with median in-state tuition of $30,566. CDC's Social Vulnerability Index places this ZIP in the 97th percentile nationally — a highly vulnerable community profile. The most recent FEMA disaster declaration here was winter storm-related (SEVERE WINTER STORM, 2025). Fast-food restaurants outnumber grocery stores roughly 6-to-1 per capita (USDA Food Environment Atlas) — a "food swamp" pattern often linked to higher diet-related disease prevalence. New residents arriving here predominantly come from Dakota County, NE (IRS SOI Migration, 2022-2023). 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 $43,977, fair market rent of $1,190 for a two-bedroom, and a low 0.0% poverty rate. 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
Sioux City, IA (ZIP 51111) sits in Woodbury County within the Sioux City metro area. The page draws on 1 federal data feed retrieved Apr 24. Top health signal: Obesity comes in above the national average at 41.1%. No NCES schools are mapped to this ZIP in the current dataset. 5 colleges and universities serve the area, with median in-state tuition of $30,566. CDC's Social Vulnerability Index places this ZIP in the 97th percentile nationally — a highly vulnerable community profile. The most recent FEMA disaster declaration here was winter storm-related (SEVERE WINTER STORM, 2025). Fast-food restaurants outnumber grocery stores roughly 6-to-1 per capita (USDA Food Environment Atlas) — a "food swamp" pattern often linked to higher diet-related disease prevalence. New residents arriving here predominantly come from Dakota County, NE (IRS SOI Migration, 2022-2023). 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 $43,977, fair market rent of $1,190 for a two-bedroom, and a low 0.0% poverty rate. 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.
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.
