Oak Park, CA population, income and ZIP codes

Oak Park CDP is a mid-size town in California, with 13,656 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #423 of 1,618 ranked by population — larger than 73% of them. The median age here is 41.4 years against 39.1 nationally, a slightly older profile than the country as a whole. Places under 65,000 residents only appear in the five-year release, never the one-year file, so these values pool sixty months of responses and lag the current year by design.

Households in Oak Park CDP earn a median of $160,484 a year, 104.3% above the national figure of $78,538 and 76% 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 3.3% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Oak Park CDP is valued at $1,017,100, 235.2% above the national figure and 73% above the $589,600 peer median, while median gross rent runs $3,150 a month, 124% above the national figure, or roughly $37,800 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 6.3×, 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. 71.8% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. 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.

Home values sit at 6.3× 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.

No figure on this page is estimated by us; each one comes straight from the published ACS tables for this area. 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.
