Clayton city, CA in context

How this area compares with national benchmarks.

Clayton city is a mid-size town in California, with 10,962 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #475 of 1,618 ranked by population — larger than 70% of them. The median age here is 44.3 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 Clayton city earn a median of $172,226 a year, 119.3% above the national figure of $78,538 and 89% 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 2.2% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Clayton city is valued at $1,017,300, 235.3% above the national figure and 73% above the $589,600 peer median, while median gross rent runs $3,501 a month, 149% above the national figure, or roughly $42,012 across a full year. A household on the local median income would put about 24.4% 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 5.9×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 90.3% 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.
