Fresh.Data current as of Apr 24, 2026
Porterville, CA (ZIP 93257) sits in Tulare County within the Visalia metro area. The page draws on 2 federal data feeds retrieved Apr 26. Top health signal: Annual Checkup comes in above the national average at 67.5%. NCES lists 34 schools serving the area, 34 non-charter. 10 colleges and universities serve the area, with median in-state tuition of $1,384. 30% of returns claim the Earned Income Tax Credit (IRS), a higher share than most ZIPs. BLS LAUS records a 10.3% county unemployment rate (2024) — about 6.3 points above the US average and a labor-market distress signal. CDC's Social Vulnerability Index places this ZIP in the 89th percentile nationally — a highly vulnerable community profile. FEMA has issued 23 federal disaster declarations affecting this ZIP since 1967 — a high-frequency exposure profile. Annual precipitation averages just 12.1" per NOAA's 1991–2020 Normals — an arid-climate ZCTA where landscaping and water-budget choices matter more than national averages suggest. 26% of adults self-report fair or poor health (County Health Rankings, 2025) — above the national county median. California levies a graduated state income tax (top rate 13.30%); a household at the local median AGI of $50,979 would pay roughly $4,068/year before deductions. IRS migration data (2022-2023) shows a net loss of 2,221 residents (1,502 households) — the ZIP's primary county is shrinking. Schools are the headline here — lots of options at varying types — while healthcare access numbers suggest worth-shopping coverage and provider choice carefully. Notable: median household income $54,889, fair market rent of $1,430 for a two-bedroom, and a typical home value of $326,611, up 0.4% 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.
