Castle Shannon, PA population, income and ZIP codes

Castle Shannon borough is a mid-size town in Pennsylvania, with 8,237 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #133 of 2,002 ranked by population — larger than 93% of them. The median age here is 41.9 years against 39.1 nationally, a slightly older profile than the country as a whole. 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 Castle Shannon borough earn a median of $62,426 a year, 20.5% below the national figure of $78,538 and 12% 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 8.4% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Castle Shannon borough is valued at $182,400, 39.9% below the national figure and 6% below the $193,200 peer median, while median gross rent runs $1,002 a month, 28.7% below the national figure, or roughly $12,024 across a full year. A household on the local median income would put about 19.3% 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 2.9×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 60.9% 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.
