ZIP Code 52003

Households in ZIP code 52003, part of the Dubuque area, earn a median of $98,908, with per-capita income at $52,172 — placing the area squarely in middle- to upper-middle-income territory rather than among the affluent. Homes carry a median value of $286,100, and the county-level property tax rate of 1.23% means owners pay roughly $3,500 annually on a house at that value. Add a combined sales tax of 7.00%, and the overall tax picture stays moderate: enough to fund local services without heavily eroding incomes that sit well above many parts of Iowa.
