Penngrove, CA population, income and ZIP codes

Penngrove CDP is a small town in California, with 2,123 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #886 of 1,618 ranked by population — larger than 45% of them. The median age here is 55.3 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 Penngrove CDP earn a median of $115,826 a year, 47.5% above the national figure of $78,538 and 27% 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 10.9% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Penngrove CDP is valued at $1,193,100, 293.2% above the national figure and 102% above the $589,600 peer median, while median gross rent runs $2,454 a month, 74.5% above the national figure, or roughly $29,448 across a full year. A household on the local median income would put about 25.4% 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 10.3×, against roughly 3.9× nationally, so buying is out of reach on local earnings alone and the ownership market leans on outside income, equity or dual high earners. 63% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.

Home values sit at 10.3× median household income, far past the 3.9× national mark, so ownership costs here are set by something other than local wages — second homes, retirees with equity, or commuters earning elsewhere. A median age of 55.3 puts Penngrove CDP 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.

All values below were released by the Census for this exact geography, with no gap-filling on our side. 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.
