El Sobrante (Contra Costa Co.), CA population, income and ZIP codes

El Sobrante CDP (Contra Costa County) is a mid-size town in California, with 15,823 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #396 of 1,618 ranked by population — larger than 75% of them. The median age here is 39.7 years against 39.1 nationally, a slightly older profile than the country as a whole. 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 El Sobrante CDP (Contra Costa County) earn a median of $112,622 a year, 43.4% above the national figure of $78,538 and 24% 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 9.8% of residents here, below the 12.4% national rate.

The typical owner-occupied home in El Sobrante CDP (Contra Costa County) is valued at $695,900, 129.4% above the national figure and 18% above the $589,600 peer median, while median gross rent runs $2,245 a month, 59.7% above the national figure, or roughly $26,940 across a full year. A household on the local median income would put about 23.9% 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 6.2×, 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. 65.2% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. Rent is reported gross — contract rent plus tenant-paid utilities — which is why it runs above the advertised price on a listing for the same unit.

Home values sit at 6.2× 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.

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.
