Upper Lake, CA population, income and ZIP codes

Upper Lake CDP is a small town in California, with 1,204 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #1011 of 1,618 ranked by population — larger than 37% of them. The median age here is 48 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 Upper Lake CDP earn a median of $104,936 a year, 33.6% above the national figure of $78,538 and 15% above the $91,111 median for the 1,050 California cities we cover. The median is the midpoint household, not an average, so a handful of very high earners cannot drag it upward the way they distort a mean. Poverty reaches 8.5% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Upper Lake CDP is valued at $344,000, 13.4% above the national figure and 42% below the $589,600 peer median, while median gross rent runs not published a month. The home-price-to-income ratio works out to 3.3×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 91.3% 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.

The Census withheld gross rent for Upper Lake CDP because the sample was too thin to publish at this geography. Those values were suppressed at the source, not lost in our dataset, and we do not model a replacement. Everything else on this page comes straight from the ACS 2019-2023 ACS 5-year tables.
