Grantley, PA population, income and ZIP codes

Grantley CDP is a small town in Pennsylvania, with 4,762 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #291 of 2,002 ranked by population — larger than 85% of them. The median age here is 21.3 years against 39.1 nationally, a distinctly younger profile, typical of places with students, military posts or a fast-growing family population. 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 Grantley CDP earn a median of $121,563 a year, 54.8% above the national figure of $78,538 and 71% above 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 6% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Grantley CDP is valued at $404,100, 33.2% above the national figure and 109% above the $193,200 peer median, while median gross rent runs $1,548 a month, 10.1% above the national figure, or roughly $18,576 across a full year. A household on the local median income would put about 15.3% 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. 88.5% of occupied homes are owner-occupied versus 65% nationally, an owner-dominated market where rental listings are scarce and rent medians rest on a thin sample. 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 21.3 means a large student or early-career population; income medians in places like this understate household resources, since many residents are supported from outside the address.

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.
