The table below lists every ZIP by population, so you can see which neighborhoods carry the weight of the city total and which are smaller pockets of the same municipal boundary.

Aggregated across every ZIP in Bethlehem, the median household income averages $88,389 and per-capita income averages $46,617. Poverty rate runs at 11.8% and unemployment at 5.5%.
