Guerneville, CA (ZIP 95446) sits in Sonoma County within the Santa Rosa-Petaluma metro area. The page draws on 2 federal data feeds retrieved Apr 26. Top health signal: Health Insurance comes in below the national average at 5.8%. NCES lists 2 schools serving the area, 2 non-charter. 5 colleges and universities serve the area, with median in-state tuition of $1,423. IRS data shows average household income (AGI) of $82,259, well above the ~$45K national average per return. 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. FEMA has issued 36 federal disaster declarations affecting this ZIP since 1964 — a high-frequency exposure profile. Median daily AQI is just 19 per EPA AQS (2024), comfortably inside the Good range, with PM2.5 as the primary pollutant on most measured days. California levies a graduated state income tax (top rate 13.30%); a household at the local median AGI of $82,259 would pay roughly $6,564/year before deductions. New residents arriving here predominantly come from Marin County, CA (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 $82,706, fair market rent of $2,470 for a two-bedroom, and a typical home value of $522,103, down 6.6% 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.

Guerneville, CA (ZIP 95446) sits in Sonoma County within the Santa Rosa-Petaluma metro area. The page draws on 2 federal data feeds retrieved Apr 26. Top health signal: Health Insurance comes in below the national average at 5.8%. NCES lists 2 schools serving the area, 2 non-charter. 5 colleges and universities serve the area, with median in-state tuition of $1,423. IRS data shows average household income (AGI) of $82,259, well above the ~$45K national average per return. 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. FEMA has issued 36 federal disaster declarations affecting this ZIP since 1964 — a high-frequency exposure profile. Median daily AQI is just 19 per EPA AQS (2024), comfortably inside the Good range, with PM2.5 as the primary pollutant on most measured days. California levies a graduated state income tax (top rate 13.30%); a household at the local median AGI of $82,259 would pay roughly $6,564/year before deductions. New residents arriving here predominantly come from Marin County, CA (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 $82,706, fair market rent of $2,470 for a two-bedroom, and a typical home value of $522,103, down 6.6% 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 23.9%. 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.
