ZIP code 18052

ZIP 18052 is a small city in Lehigh County, Pennsylvania, with 29,271 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #114 of 1,833 ranked by population — larger than 93% of them. The median age here is 39.6 years against 39.1 nationally, a slightly older 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 ZIP 18052 earn a median of $69,499 a year, 11.5% below the national figure of $78,538. Median household income counts every pre-tax dollar arriving at an address — wages, self-employment, Social Security, pensions, interest and public assistance — for everyone living there, so multi-earner households pull the figure up even where individual pay is modest. Poverty reaches 10.8% of residents here, below the 12.4% national rate.

The typical owner-occupied home in ZIP 18052 is valued at $247,100, 18.6% below the national figure, while median gross rent runs $1,387 a month, 1.4% below the national figure, or roughly $16,644 across a full year. A household on the local median income would put about 23.9% 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 3.6×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 62.2% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. Rent is reported gross — contract rent plus tenant-paid utilities — which is why it runs above the advertised price on a listing for the same unit.

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.

Pennsylvania charges 6% statewide, and local governments overlapping 18052 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 18052 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.
