Camp Pendleton Mainside, CA population, income and ZIP codes

Camp Pendleton Mainside CDP is a mid-size town in California, with 9,801 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #504 of 1,618 ranked by population — larger than 68% of them. The median age here is 21.6 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 Camp Pendleton Mainside CDP earn a median of $56,250 a year, 28.4% below the national figure of $78,538 and 38% below 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 10.7% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Camp Pendleton Mainside CDP is valued at not published, while median gross rent runs $3,501 a month, 149% above the national figure, or roughly $42,012 across a full year. A household on the local median income would put about 74.7% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is severely stretched — a median-income renter clears the cost-burden line by a wide margin before utilities beyond the gross-rent definition. 0% of occupied homes are owner-occupied versus 65% nationally, a renter-majority market, so rent figures matter more here than the home-value line. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.

A median age of 21.6 means a large student or early-career population; income medians in places like this understate household resources, since many residents are supported from outside the address.

The Census withheld home value for Camp Pendleton Mainside CDP because the sample was too thin to publish at this geography. Those values were suppressed at the source, not lost in our dataset, and we do not model a replacement. Everything else on this page comes straight from the ACS 2019-2023 ACS 5-year tables.
