Williams, CA population, income and ZIP codes

Williams city is a mid-size town in California, with 5,569 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #634 of 1,618 ranked by population — larger than 60% of them. The median age here is 30.5 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 Williams city earn a median of $93,138 a year, 18.6% above the national figure of $78,538 and within a couple of points of the $91,111 median for the 1,050 California cities we cover. Median household income counts every pre-tax dollar arriving at an address — wages, self-employment, Social Security, pensions, interest and public assistance — for everyone living there, so multi-earner households pull the figure up even where individual pay is modest. Poverty reaches 5.9% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Williams city is valued at $339,900, 12% above the national figure and 42% below the $589,600 peer median, while median gross rent runs $1,296 a month, 7.8% below the national figure, or roughly $15,552 across a full year. A household on the local median income would put about 16.7% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is cheap relative to what people here earn. The home-price-to-income ratio works out to 3.6×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 49.4% 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.

Every value on this page is published directly by the Census for this area — nothing is modelled or interpolated. 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.
