Irwin borough, PA in context

How this area compares with national benchmarks.

Irwin borough is a small town in Pennsylvania, with 3,862 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #379 of 2,002 ranked by population — larger than 81% of them. The median age here is 38.5 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 Irwin borough earn a median of $60,747 a year, 22.7% below the national figure of $78,538 and 15% below the $71,118 median for the 982 Pennsylvania cities we cover. Median household income counts every pre-tax dollar arriving at an address — wages, self-employment, Social Security, pensions, interest and public assistance — for everyone living there, so multi-earner households pull the figure up even where individual pay is modest. Poverty reaches 16.8% of residents here, above the 12.4% national rate.

The typical owner-occupied home in Irwin borough is valued at $198,700, 34.5% below the national figure and 3% above the $193,200 peer median, while median gross rent runs $954 a month, 32.1% below the national figure, or roughly $11,448 across a full year. A household on the local median income would put about 18.8% 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 3.3×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 45.3% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. 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.
