Katy (77450): Neighborhood Profile

Katy (ZIP 77450) is a densely settled Houston neighborhood, home to about 73,226 people across 14 square miles — roughly 5,230 residents per square mile. It has the texture of an established inner-ring community: a mix of older single-family stock and newer infill, with daily errands rarely more than a few minutes away. Economically it skews upper-middle: a median household income of $105,607 sits 24% above the Houston median of $84,833, the kind of figure typical of dual-income professional and managerial households.

The population skews prime working age (median age 37.6) and family-oriented, with an average household of 2.89 people. With a diversity index of 56/100, 77450 is more racially and ethnically diverse than the typical Houston ZIP. The largest groups are White (60.9%) and Hispanic or Latino (22.3%).

Put in context, 77450's median home value of $342,000 sits 13% above the Houston-area median home value of $301,548. That places local home values above the national median (around $340,000), though still well under coastal-metro pricing in California or the Northeast. Educational attainment — 52.6% of adults hold a bachelor's degree, versus the 35% metro average — reinforces the area's higher-skill, higher-earning profile.
