Sioux City, IA (ZIP 51109) sits in Plymouth County. The page draws on 2 federal data feeds retrieved Apr 27. Top health signal: Obesity comes in above the national average at 40.7%. NCES lists 1 schools serving the area, 1 non-charter. 5 colleges and universities serve the area, with median in-state tuition of $30,566. IRS data shows average household income (AGI) of $55,690 per tax return. Local establishments report average pay of $26,521 per worker (Census ZBP) — below the US average. BLS LAUS reports county unemployment of just 2.4% (2024), well below the ~4.0% US average and consistent with a tight local labor market. The CDC SVI flags household composition (87th percentile) as this ZIP's standout vulnerability dimension, sitting well above its overall 50th-percentile score. FEMA has issued 20 federal disaster declarations affecting this ZIP since 1965 — a high-frequency exposure profile. Only 4.6% of residents under 65 are uninsured (County Health Rankings, 2025) — well below the national county median. Fast-food restaurants outnumber grocery stores roughly 5-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 Woodbury County, IA (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.

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 51109) sits in Plymouth County. The page draws on 2 federal data feeds retrieved Apr 27. Top health signal: Obesity comes in above the national average at 40.7%. NCES lists 1 schools serving the area, 1 non-charter. 5 colleges and universities serve the area, with median in-state tuition of $30,566. IRS data shows average household income (AGI) of $55,690 per tax return. Local establishments report average pay of $26,521 per worker (Census ZBP) — below the US average. BLS LAUS reports county unemployment of just 2.4% (2024), well below the ~4.0% US average and consistent with a tight local labor market. The CDC SVI flags household composition (87th percentile) as this ZIP's standout vulnerability dimension, sitting well above its overall 50th-percentile score. FEMA has issued 20 federal disaster declarations affecting this ZIP since 1965 — a high-frequency exposure profile.

Fast-food restaurants outnumber grocery stores roughly 5-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 Woodbury County, IA (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 $73,158, fair market rent of $1,120 for a two-bedroom, and a typical home value of $173,905, up 9.3% 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 21.0%. 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.
