ZIP 95521 in context
How this area compares with national benchmarks.
ZIP 95521 is a mid-size town in Humboldt County, California, with 21,684 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #780 of 1,803 ranked by population — larger than 56% of them. The median age here is 29.2 years against 39.1 nationally, a distinctly younger profile, typical of places with students, military posts or a fast-growing family population. Places under 65,000 residents only appear in the five-year release, never the one-year file, so these values pool sixty months of responses and lag the current year by design.
Households in ZIP 95521 earn a median of $54,324 a year, 30.8% below the national figure of $78,538. Household income here is measured before tax and pooled across everyone at the address, which is why it reads higher than typical individual earnings in the same area. Poverty reaches 26.7% of residents here, well above the 12.4% national rate, which is the single clearest signal in this dataset that median income here is carried by a narrow band of households.
The typical owner-occupied home in ZIP 95521 is valued at $478,600, 57.7% above the national figure, while median gross rent runs $1,300 a month, 7.5% below the national figure, or roughly $15,600 across a full year. A household on the local median income would put about 28.7% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is within the standard affordability guideline. The home-price-to-income ratio works out to 8.8×, against roughly 3.9× nationally, so buying is out of reach on local earnings alone and the ownership market leans on outside income, equity or dual high earners. 36.7% of occupied homes are owner-occupied versus 65% nationally, a renter-majority market, so rent figures matter more here than the home-value line. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.
Home values sit at 8.8× median household income, far past the 3.9× national mark, so ownership costs here are set by something other than local wages — second homes, retirees with equity, or commuters earning elsewhere. A median age of 29.2 means a large student or early-career population; income medians in places like this understate household resources, since many residents are supported from outside the address.
No figure on this page is estimated by us; each one comes straight from the published ACS tables for this area. Small-area estimates still carry wider margins of error than state or national figures, so check the linked ACS tables before relying on them for lending, appraisal or legal work.
Reading ZIP 95521 in context
How 95521 sits inside Humboldt County and California.
ZIP 95521 is tabulated inside Humboldt County, California, one of 35 ZIP areas the Census publishes for that county and 1,803 across California. This is a mid-sized suburban ZIP inside a county that is split across many delivery areas. County assignment on this page follows the largest share of the ZIP's land area, which matters where a delivery route crosses a county line: mail addressed to 95521 can be handled by a post office in a neighbouring county even though the tabulation area is filed here.
Against its own county, 95521 reports a median household income of $54,324, 15% below the $63,798 county median, and 40% below the $89,916 typical CA ZIP. Owner-occupied homes are valued at a median of $478,600, 11% above the county figure and 24% below the statewide ZIP median. Rent is reported gross — the contract amount plus tenant-paid utilities — at $1,300 a month, which is why it reads higher than the advertised rent on a listing for the same unit.
California charges 7.25% statewide, and local governments overlapping 95521 may add county, city or special-district levies on top. We publish the state floor for this ZIP rather than guessing a combined figure, because ZIP boundaries and taxing-district boundaries were drawn for different purposes and do not line up.
Everything above comes from the Census Bureau American Community Survey 2019-2023 ACS 5-year estimates for this ZIP Code Tabulation Area, with sales tax rates traced to the state revenue agency. Five-year estimates pool sixty months of responses, so they are stable enough to compare 95521 with its neighbours but always trail the current year, and any value the Census suppressed for sample size is shown as unpublished rather than filled in with a model.

Affordability in this ZIP
Derived from the Census medians above — indicative, not an offer.
A rent burden above 30% is the federal threshold for cost-burdened households, and a price-to-income multiple above 4× is generally considered a stretched housing market. The mortgage figure is principal and interest only — taxes, insurance and HOA dues are extra.
