Alto, CA population, income and ZIP codes

Alto CDP is a very small community in California, with 866 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #1102 of 1,618 ranked by population — larger than 31% of them. The median age here is 45.4 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 Alto CDP earn a median of not published a year. 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 4.2% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Alto CDP is valued at $2,000,001, 559.2% above the national figure and 239% above the $589,600 peer median, while median gross rent runs not published a month. 45.7% 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.

The Census withheld household income, gross rent for Alto 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.
