Alta, CA population, income and ZIP codes

Alta CDP is a very small community in California, with 740 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #1140 of 1,618 ranked by population — larger than 29% of them. The median age here is 46.8 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 Alta CDP earn a median of $94,718 a year, 20.6% above the national figure of $78,538 and 4% above 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 5.8% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Alta CDP is valued at $468,200, 54.3% above the national figure and 21% below the $589,600 peer median, while median gross rent runs not published a month. 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. 90.4% 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.

With 740 residents, a handful of survey responses moves every median on this page. Compare Alta CDP against its county rather than against national figures.

The Census withheld gross rent for Alta 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.
