Cairnbrook, PA population, income and ZIP codes

Cairnbrook CDP is a very small community in Pennsylvania, with 469 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #1383 of 2,002 ranked by population — larger than 30% of them. The median age here is 36.5 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 Cairnbrook CDP earn a median of $55,938 a year, 28.8% below the national figure of $78,538 and 21% 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 Cairnbrook CDP is valued at $83,300, 72.5% below the national figure and 57% below the $193,200 peer median, while median gross rent runs $772 a month, 45.1% below the national figure, or roughly $9,264 across a full year. A household on the local median income would put about 16.6% 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. 81.4% 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.

With 469 residents, a handful of survey responses moves every median on this page. Compare Cairnbrook CDP against its county rather than against national figures.
