Oil City, PA population, income and ZIP codes

Oil City city is a mid-size town in Pennsylvania, with 9,517 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #99 of 2,002 ranked by population — larger than 95% of them. The median age here is 42.5 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 Oil City city earn a median of $52,688 a year, 32.9% below the national figure of $78,538 and 26% below the $71,118 median for the 982 Pennsylvania 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 18% of residents here, above the 12.4% national rate.

The typical owner-occupied home in Oil City city is valued at $66,600, 78% below the national figure and 66% below the $193,200 peer median, while median gross rent runs $799 a month, 43.2% below the national figure, or roughly $9,588 across a full year. A household on the local median income would put about 18.2% 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 1.3×, against roughly 3.9× nationally, so purchase prices are unusually low against local pay, the pattern in places where supply is plentiful and wage growth has been flat. 61.4% 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.

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.
