Millville, CA population, income and ZIP codes

Millville CDP is a very small community in California, with 835 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #1109 of 1,618 ranked by population — larger than 31% of them. The median age here is 46.4 years against 39.1 nationally, a markedly older profile that usually tracks retirees staying put and younger households leaving for work. 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 Millville CDP earn a median of $113,750 a year, 44.8% above the national figure of $78,538 and 25% above 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 4.4% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Millville CDP is valued at $466,700, 53.8% above the national figure and 21% below the $589,600 peer median, while median gross rent runs $1,648 a month, 17.2% above the national figure, or roughly $19,776 across a full year. A household on the local median income would put about 17.4% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is cheap relative to what people here earn. The home-price-to-income ratio works out to 4.1×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 85.6% 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. 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.

With 835 residents, a handful of survey responses moves every median on this page. Compare Millville CDP against its county rather than against national figures.

Every value on this page is published directly by the Census for this area — nothing is modelled or interpolated. 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.
