Fresh.Data current as of Apr 24, 2026
Whittier, CA (ZIP 90603) sits in Los Angeles County within the Los Angeles-Long Beach-Anaheim metro area. The page draws on 2 federal data feeds retrieved Apr 26. Top health signal: Obesity comes in below the national average at 25.1%. NCES lists 3 schools serving the area, 3 non-charter. 10 colleges and universities serve the area, with median in-state tuition of $9,329. IRS data shows average household income (AGI) of $102,141, well above the ~$45K national average per return. BLS QCEW puts average annual pay at $83,554 per worker — about 28% above the US average and a clear high-wage signal. The CDC SVI flags racial & ethnic minority (78th percentile) as this ZIP's standout vulnerability dimension, sitting well above its overall 43th-percentile score. FEMA has issued 88 federal disaster declarations affecting this ZIP since 1969 — a high-frequency exposure profile. Annual precipitation averages just 13.5" per NOAA's 1991–2020 Normals — an arid-climate ZCTA where landscaping and water-budget choices matter more than national averages suggest. EPA AQS records a median daily AQI of 80 for the primary county (2024) — in the Moderate-to-Unhealthy band, with ozone as the primary pollutant on most measured days. 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. California levies a graduated state income tax (top rate 13.30%); a household at the local median AGI of $102,141 would pay roughly $8,151/year before deductions. IRS migration data (2022-2023) shows a net loss of 89,357 residents (41,326 households) — the ZIP's primary county is shrinking. 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 $117,324, fair market rent of $3,430 for a two-bedroom, and a typical home value of $892,748, up 0.3% 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.

What these numbers say together
Whittier, CA (ZIP 90603) sits in Los Angeles County within the Los Angeles-Long Beach-Anaheim metro area. The page draws on 2 federal data feeds retrieved Apr 26. Top health signal: Obesity comes in below the national average at 25.1%. NCES lists 3 schools serving the area, 3 non-charter. 10 colleges and universities serve the area, with median in-state tuition of $9,329. IRS data shows average household income (AGI) of $102,141, well above the ~$45K national average per return. BLS QCEW puts average annual pay at $83,554 per worker — about 28% above the US average and a clear high-wage signal. The CDC SVI flags racial & ethnic minority (78th percentile) as this ZIP's standout vulnerability dimension, sitting well above its overall 43th-percentile score. FEMA has issued 88 federal disaster declarations affecting this ZIP since 1969 — a high-frequency exposure profile. Annual precipitation averages just 13.5" per NOAA's 1991–2020 Normals — an arid-climate ZCTA where landscaping and water-budget choices matter more than national averages suggest. EPA AQS records a median daily AQI of 80 for the primary county (2024) — in the Moderate-to-Unhealthy band, with ozone as the primary pollutant on most measured days. 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. California levies a graduated state income tax (top rate 13.30%); a household at the local median AGI of $102,141 would pay roughly $8,151/year before deductions. IRS migration data (2022-2023) shows a net loss of 89,357 residents (41,326 households) — the ZIP's primary county is shrinking. 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 $117,324, fair market rent of $3,430 for a two-bedroom, and a typical home value of $892,748, up 0.3% 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 lower the national rate at 18.5%. 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.
