Williamstown, PA population, income and ZIP codes

Williamstown borough is a small town in Pennsylvania, with 1,289 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #867 of 2,002 ranked by population — larger than 56% of them. The median age here is 40.8 years against 39.1 nationally, a slightly older 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 Williamstown borough earn a median of $61,875 a year, 21.2% below the national figure of $78,538 and 13% 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 22.2% 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 Williamstown borough is valued at $95,200, 68.6% below the national figure and 51% below the $193,200 peer median, while median gross rent runs $917 a month, 34.8% below the national figure, or roughly $11,004 across a full year. A household on the local median income would put about 17.8% 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 1.5×, 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. 62.8% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

Every value on this page is published directly by the Census for this area — nothing is modelled or interpolated. 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.
