Berwick's 03903 ZIP code sits in solidly middle-income territory, with a median household income of $101,522 and per-capita income of $57,293. Homes here carry a median value of $498,900, and the county-level effective property tax rate of 0.96% means owners pay roughly $4,790 annually on a house at that price.
