Fullerton, CA population, income and ZIP codes

Fullerton city is a mid-size city in California, with 141,278 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #42 of 1,618 ranked by population — larger than 97% of them. The median age here is 36.1 years against 39.1 nationally, a slightly younger profile than the country as a whole. At this size the Census also publishes one-year estimates; the five-year values used here are steadier and let you compare against smaller neighbours on the same basis.

Households in Fullerton city earn a median of $104,219 a year, 32.7% above the national figure of $78,538 and 14% 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 12.2% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Fullerton city is valued at $859,600, 183.3% above the national figure and 46% above the $589,600 peer median, while median gross rent runs $2,124 a month, 51.1% above the national figure, or roughly $25,488 across a full year. A household on the local median income would put about 24.5% 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 8.2×, against roughly 3.9× nationally, so buying is out of reach on local earnings alone and the ownership market leans on outside income, equity or dual high earners. 51.5% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

Home values sit at 8.2× median household income, far past the 3.9× national mark, so ownership costs here are set by something other than local wages — second homes, retirees with equity, or commuters earning elsewhere.

All values below were released by the Census for this exact geography, with no gap-filling on our side. Small-area estimates still carry wider margins of error than state or national figures, so check the linked ACS tables before relying on them for lending, appraisal or legal work.
