Hamilton City CDP, CA in context

How this area compares with national benchmarks.

Hamilton City CDP is a small town in California, with 2,295 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #867 of 1,618 ranked by population — larger than 46% of them. The median age here is 25 years against 39.1 nationally, a distinctly younger profile, typical of places with students, military posts or a fast-growing family population. 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 Hamilton City CDP earn a median of $70,665 a year, 10% below the national figure of $78,538 and 22% below the $91,111 median for the 1,050 California cities we cover. This figure covers the household, not the worker: two people on ordinary wages at one address outrank a single professional in the same table. Poverty reaches 7.5% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Hamilton City CDP is valued at $278,800, 8.1% below the national figure and 53% below the $589,600 peer median, while median gross rent runs $865 a month, 38.5% below the national figure, or roughly $10,380 across a full year. A household on the local median income would put about 14.7% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is cheap relative to what people here earn. The home-price-to-income ratio works out to 3.9×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 62.4% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. 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.

A median age of 25 means a large student or early-career population; income medians in places like this understate household resources, since many residents are supported from outside the address.
