Isleton, CA population, income and ZIP codes

Isleton city is a very small community in California, with 649 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #1168 of 1,618 ranked by population — larger than 27% of them. The median age here is 32.3 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 Isleton city earn a median of $59,250 a year, 24.6% below the national figure of $78,538 and 35% 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 20.2% 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 Isleton city is valued at $316,900, 4.4% above the national figure and 46% below the $589,600 peer median, while median gross rent runs $1,164 a month, 17.2% below the national figure, or roughly $13,968 across a full year. A household on the local median income would put about 23.6% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is within the standard affordability guideline. The home-price-to-income ratio works out to 5.3×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 75.9% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

With 649 residents, a handful of survey responses moves every median on this page. Compare Isleton city against its county rather than against national figures.
