Walnut Grove, CA population, income and ZIP codes

Walnut Grove CDP is a very small community in California, with 970 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #1065 of 1,618 ranked by population — larger than 34% of them. The median age here is 33.9 years against 39.1 nationally, a slightly younger 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 Walnut Grove CDP earn a median of $88,269 a year, 12.4% above the national figure of $78,538 and 3% 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 13.7% of residents here, above the 12.4% national rate.

The typical owner-occupied home in Walnut Grove CDP is valued at $657,800, 116.8% above the national figure and 12% above the $589,600 peer median, while median gross rent runs $1,380 a month, 1.8% below the national figure, or roughly $16,560 across a full year. A household on the local median income would put about 18.8% 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 7.5×, 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. 52.9% 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 7.5× 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. Median income runs above the national figure while poverty also runs above it — a split distribution, not a uniformly comfortable place. Averages hide that; the two numbers together do not.

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.
