Rio Vista, CA population, income and ZIP codes

Rio Vista city is a mid-size town in California, with 10,002 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #502 of 1,618 ranked by population — larger than 69% of them. The median age here is 64.7 years against 39.1 nationally, a markedly older profile that usually tracks retirees staying put and younger households leaving for work. 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 Rio Vista city earn a median of $86,970 a year, 10.7% above the national figure of $78,538 and 5% below 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 8% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Rio Vista city is valued at $480,300, 58.3% above the national figure and 19% below the $589,600 peer median, while median gross rent runs $1,624 a month, 15.5% above the national figure, or roughly $19,488 across a full year. A household on the local median income would put about 22.4% 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 5.5×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 80.9% of occupied homes are owner-occupied versus 65% nationally, an owner-dominated market where rental listings are scarce and rent medians rest on a thin sample. 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 64.7 puts Rio Vista city well into retirement-weighted territory, which pulls median household income down even where household wealth is high, because retirement draws are counted differently from wages.
