Clay County · Population 93
Fostoria, IA (ZIP 51340) sits in Clay County. The page draws on 1 federal data feed retrieved Apr 24. Top health signal: Health Insurance comes in below the national average at 6.3%. No NCES schools are mapped to this ZIP in the current dataset. 2 colleges and universities serve the area, with median in-state tuition of $7,392. 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. Social vulnerability is low in this ZIP at the 16th percentile (CDC SVI), reflecting strong baseline resilience to public-health emergencies and natural disasters. FEMA has issued 21 federal disaster declarations affecting this ZIP since 1965 — a high-frequency exposure profile. Only 4.9% 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 Dickinson 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 $80,000, fair market rent of $920 for a two-bedroom, and a typical home value of $145,861, up 8.2% 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 lower the national rate at 19.7%. 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.
