Johnstonville, CA population, income and ZIP codes

Johnstonville CDP is a very small community in California, with 967 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #1068 of 1,618 ranked by population — larger than 34% of them. The median age here is 41.5 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 Johnstonville CDP earn a median of $98,188 a year, 25% above the national figure of $78,538 and 8% above 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 2.7% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Johnstonville CDP is valued at $278,900, 8.1% below the national figure and 53% below the $589,600 peer median, while median gross rent runs $1,335 a month, 5% below the national figure, or roughly $16,020 across a full year. A household on the local median income would put about 16.3% 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 2.8×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 87.8% of occupied homes are owner-occupied versus 65% nationally, an owner-dominated market where rental listings are scarce and rent medians rest on a thin sample. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

With 967 residents, a handful of survey responses moves every median on this page. Compare Johnstonville CDP against its county rather than against national figures.

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.
