Grover Beach, CA population, income and ZIP codes

Grover Beach city is a mid-size town in California, with 12,687 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #440 of 1,618 ranked by population — larger than 72% of them. The median age here is 40.5 years against 39.1 nationally, a slightly older profile than the country as a whole. 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 Grover Beach city earn a median of $82,534 a year, 5.1% above the national figure of $78,538 and 9% 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 12.7% of residents here, above the 12.4% national rate.

The typical owner-occupied home in Grover Beach city is valued at $691,900, 128% above the national figure and 17% above the $589,600 peer median, while median gross rent runs $1,921 a month, 36.6% above the national figure, or roughly $23,052 across a full year. A household on the local median income would put about 27.9% 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 8.4×, 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. 55.4% 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 8.4× 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. Median income runs above the national figure while poverty also runs above it — a split distribution, not a uniformly comfortable place. Averages hide that; the two numbers together do not.
