Mount Joy, PA population, income and ZIP codes

Mount Joy borough is a mid-size town in Pennsylvania, with 8,310 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #130 of 2,002 ranked by population — larger than 93% of them. The median age here is 38.7 years against 39.1 nationally, a slightly younger 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 Mount Joy borough earn a median of $84,514 a year, 7.6% above the national figure of $78,538 and 19% above the $71,118 median for the 982 Pennsylvania cities we cover. Household income here is measured before tax and pooled across everyone at the address, which is why it reads higher than typical individual earnings in the same area.

The typical owner-occupied home in Mount Joy borough is valued at $241,300, 20.5% below the national figure and 25% above the $193,200 peer median, while median gross rent runs $1,070 a month, 23.9% below the national figure, or roughly $12,840 across a full year. A household on the local median income would put about 15.2% 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. 61.5% 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.
