Northumberland ZIP codes — Northumberland County, Pennsylvania

Northumberland County is a small city in Pennsylvania, with 90,925 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates. The median age here is 44.4 years against 39.1 nationally, a slightly older profile than the country as a whole. At this size the Census also publishes one-year estimates; the five-year values used here are steadier and let you compare against smaller neighbours on the same basis.

Households in Northumberland County earn a median of $57,948 a year, 26.2% below the national figure of $78,538. 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 12.2% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Northumberland County is valued at $151,600, 50% below the national figure, while median gross rent runs $777 a month, 44.7% below the national figure, or roughly $9,324 across a full year. A household on the local median income would put about 16.1% 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 2.6×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 74.8% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.
