Riverdale, CA population, income and ZIP codes

Riverdale CDP is a small town in California, with 2,803 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #811 of 1,618 ranked by population — larger than 49% of them. The median age here is 28.6 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 CDP earn a median of $54,250 a year, 30.9% below the national figure of $78,538 and 40% 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 12.3% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Riverdale CDP is valued at $265,100, 12.6% below the national figure and 55% below the $589,600 peer median, while median gross rent runs $1,095 a month, 22.1% below the national figure, or roughly $13,140 across a full year. A household on the local median income would put about 24.2% 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 4.9×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 62.6% 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 28.6 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.

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.
