What these numbers say together

Sioux City, IA (ZIP 51103) sits in Woodbury 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 42.1%. NCES lists 5 schools serving the area, 5 non-charter. 5 colleges and universities serve the area, with median in-state tuition of $30,566. 25% of returns claim the Earned Income Tax Credit (IRS), a higher share than most ZIPs. 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. CDC's Social Vulnerability Index places this ZIP in the 81th 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). 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 $55,284, fair market rent of $1,130 for a two-bedroom, and a typical home value of $155,846, up 2.2% 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.

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 20.2%. 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.
