Gonzales, CA population, income and ZIP codes

Gonzales city is a mid-size town in California, with 8,526 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #525 of 1,618 ranked by population — larger than 67% of them. The median age here is 27.9 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 Gonzales city earn a median of $76,060 a year, 3.2% below the national figure of $78,538 and 17% below the $91,111 median for the 1,050 California cities we cover. This figure covers the household, not the worker: two people on ordinary wages at one address outrank a single professional in the same table. Poverty reaches 8% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Gonzales city is valued at $593,900, 95.7% above the national figure and within a couple of points of the $589,600 peer median, while median gross rent runs $1,570 a month, 11.7% above the national figure, or roughly $18,840 across a full year. A household on the local median income would put about 24.8% 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 7.8×, 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. 57.9% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. 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 7.8× 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 27.9 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.
