Rialto, CA population, income and ZIP codes

Rialto city is a mid-size city in California, with 103,866 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #71 of 1,618 ranked by population — larger than 95% of them. The median age here is 31.8 years against 39.1 nationally, a distinctly younger profile, typical of places with students, military posts or a fast-growing family population. 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 Rialto city earn a median of $85,521 a year, 8.9% above the national figure of $78,538 and 6% 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 12.6% of residents here, above the 12.4% national rate.

The typical owner-occupied home in Rialto city is valued at $454,400, 49.8% above the national figure and 23% below the $589,600 peer median, while median gross rent runs $1,641 a month, 16.7% above the national figure, or roughly $19,692 across a full year. A household on the local median income would put about 23% 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. 64.5% 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.

Median income runs above the national figure while poverty also runs above it — a split distribution, not a uniformly comfortable place. Averages hide that; the two numbers together do not.

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.
