Jamestown, CA population, income and ZIP codes

Jamestown CDP is a small town in California, with 3,777 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #725 of 1,618 ranked by population — larger than 55% of them. The median age here is 41.8 years against 39.1 nationally, a slightly older profile than the country as a whole. At this population the ACS sample is small, so the margin of error around every dollar figure below is wide — treat the numbers as a band, not a point, and expect them to move between annual releases without the place itself changing.

Households in Jamestown CDP earn a median of $51,886 a year, 33.9% below the national figure of $78,538 and 43% below the $91,111 median for the 1,050 California cities we cover. 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 8.6% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Jamestown CDP is valued at $350,600, 15.6% above the national figure and 41% below the $589,600 peer median, while median gross rent runs $1,061 a month, 24.5% below the national figure, or roughly $12,732 across a full year. A household on the local median income would put about 24.5% 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 6.8×, 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. 58.5% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

Home values sit at 6.8× 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.

All values below were released by the Census for this exact geography, with no gap-filling on our side. 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.
