Mertztown, PA population, income and ZIP codes

Mertztown CDP is a very small community in Pennsylvania, with 630 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #1233 of 2,002 ranked by population — larger than 38% of them. The median age here is 43.7 years against 39.1 nationally, a slightly older 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 Mertztown CDP earn a median of $64,318 a year, 18.1% below the national figure of $78,538 and 10% below 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. Poverty reaches 5.6% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Mertztown CDP is valued at $173,300, 42.9% below the national figure and 10% below the $193,200 peer median, while median gross rent runs $1,150 a month, 18.2% below the national figure, or roughly $13,800 across a full year. A household on the local median income would put about 21.5% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is within the standard affordability guideline. The home-price-to-income ratio works out to 2.7×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 82.5% 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. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.
