Riverdale Park, CA population, income and ZIP codes

Riverdale Park CDP is a very small community in California, with 998 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #1058 of 1,618 ranked by population — larger than 34% of them. The median age here is 22 years against 39.1 nationally, a distinctly younger profile, typical of places with students, military posts or a fast-growing family population. 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 Riverdale Park CDP earn a median of $61,802 a year, 21.3% below the national figure of $78,538 and 32% 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 12.5% of residents here, above the 12.4% national rate.

The typical owner-occupied home in Riverdale Park CDP is valued at not published, while median gross rent runs $1,555 a month, 10.6% above the national figure, or roughly $18,660 across a full year. A household on the local median income would put about 30.2% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is a stretch on median earnings. 55.9% 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.

A median age of 22 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. With 998 residents, a handful of survey responses moves every median on this page. Compare Riverdale Park CDP against its county rather than against national figures.

The Census withheld home value for Riverdale Park 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.
