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 Katy, the median household income averages $115,349 and per-capita income averages $44,856. Poverty rate runs at 9.0% and unemployment at 5.7%. On housing, the average median home value is $362,900 with median rent of $1,911 per month, and 71.9% of occupied units are owner-occupied.
