ZIP code 15557

ZIP 15557 is a small town in Somerset County, Pennsylvania, with 3,430 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #758 of 1,833 ranked by population — larger than 58% of them. The median age here is 45.8 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 ZIP 15557 earn a median of $59,833 a year, 23.8% below the national figure of $78,538. 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 10.6% of residents here, below the 12.4% national rate.

The typical owner-occupied home in ZIP 15557 is valued at $123,900, 59.2% below the national figure, while median gross rent runs $697 a month, 50.4% below the national figure, or roughly $8,364 across a full year. A household on the local median income would put about 14% 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 2.1×, 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. 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.

No figure on this page is estimated by us; each one comes straight from the published ACS tables for this area. 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.

Against its own county, 15557 reports a median household income of $59,833, close to the $60,972 county median, and 15% below the $70,000 typical PA ZIP. Owner-occupied homes are valued at a median of $123,900, close to the county figure and 34% below the statewide ZIP median.

Pennsylvania charges 6% statewide, and local governments overlapping 15557 may add county, city or special-district levies on top. We publish the state floor for this ZIP rather than guessing a combined figure, because ZIP boundaries and taxing-district boundaries were drawn for different purposes and do not line up.

Everything above comes from the Census Bureau American Community Survey 2019-2023 ACS 5-year estimates for this ZIP Code Tabulation Area, with sales tax rates traced to the state revenue agency. Five-year estimates pool sixty months of responses, so they are stable enough to compare 15557 with its neighbours but always trail the current year, and any value the Census suppressed for sample size is shown as unpublished rather than filled in with a model.
