Mount Oliver, PA population, income and ZIP codes

Mount Oliver borough is a small town in Pennsylvania, with 3,347 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #427 of 2,002 ranked by population — larger than 78% of them. The median age here is 37.2 years against 39.1 nationally, a slightly younger profile than the country as a whole. 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 Mount Oliver borough earn a median of $50,379 a year, 35.9% below the national figure of $78,538 and 29% 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 19.2% 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 Mount Oliver borough is valued at $84,700, 72.1% below the national figure and 56% below the $193,200 peer median, while median gross rent runs $1,102 a month, 21.6% below the national figure, or roughly $13,224 across a full year. A household on the local median income would put about 26.2% 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 1.7×, 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. 42.9% of occupied homes are owner-occupied versus 65% nationally, a renter-majority market, so rent figures matter more here than the home-value line. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.

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.
