Willow Street, PA population, income and ZIP codes

Willow Street CDP is a mid-size town in Pennsylvania, with 10,010 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #87 of 2,002 ranked by population — larger than 95% of them. The median age here is 52.1 years against 39.1 nationally, a markedly older profile that usually tracks retirees staying put and younger households leaving for work. 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 Willow Street CDP earn a median of $106,867 a year, 36.1% above the national figure of $78,538 and 50% above the $71,118 median for the 982 Pennsylvania 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 3.4% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Willow Street CDP is valued at $298,200, 1.7% below the national figure and 54% above the $193,200 peer median, while median gross rent runs $2,453 a month, 74.5% above the national figure, or roughly $29,436 across a full year. A household on the local median income would put about 27.5% 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 2.8×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 43.3% of occupied homes are owner-occupied versus 65% nationally, a renter-majority market, so rent figures matter more here than the home-value line. 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.

A median age of 52.1 puts Willow Street CDP well into retirement-weighted territory, which pulls median household income down even where household wealth is high, because retirement draws are counted differently from wages.

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.
