Mainville, PA population, income and ZIP codes

Mainville CDP is a very small community in Pennsylvania, with 122 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #1851 of 2,002 ranked by population — larger than 7% of them. The median age here is 48.2 years against 39.1 nationally, a markedly older profile that usually tracks retirees staying put and younger households leaving for work. 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 Mainville CDP earn a median of $35,625 a year, 54.6% below the national figure of $78,538 and 50% below 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 41.8% 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 Mainville CDP is valued at $151,300, 50.1% below the national figure and 22% below the $193,200 peer median, while median gross rent runs $1,283 a month, 8.7% below the national figure, or roughly $15,396 across a full year. A household on the local median income would put about 43.2% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is severely stretched — a median-income renter clears the cost-burden line by a wide margin before utilities beyond the gross-rent definition. The home-price-to-income ratio works out to 4.2×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 57.4% 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.

With 122 residents, a handful of survey responses moves every median on this page. Compare Mainville CDP against its county rather than against national figures.

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.
