Clearlake, CA population, income and ZIP codes

Clearlake city is a mid-size town in California, with 16,604 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #389 of 1,618 ranked by population — larger than 76% of them. The median age here is 35.8 years against 39.1 nationally, a slightly younger 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 Clearlake city earn a median of $41,580 a year, 47.1% below the national figure of $78,538 and 54% below the $91,111 median for the 1,050 California cities we cover. Median household income counts every pre-tax dollar arriving at an address — wages, self-employment, Social Security, pensions, interest and public assistance — for everyone living there, so multi-earner households pull the figure up even where individual pay is modest. Poverty reaches 25.4% of residents here, well above the 12.4% national rate, which is the single clearest signal in this dataset that median income here is carried by a narrow band of households.

The typical owner-occupied home in Clearlake city is valued at $204,500, 32.6% below the national figure and 65% below the $589,600 peer median, while median gross rent runs $1,162 a month, 17.4% below the national figure, or roughly $13,944 across a full year. A household on the local median income would put about 33.5% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is a stretch on median earnings. The home-price-to-income ratio works out to 4.9×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 58.4% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

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.
