League City (77573): Neighborhood Profile

League City (ZIP 77573) is a densely settled Houston neighborhood, home to about 97,871 people across 22 square miles — roughly 4,449 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. By Houston standards this is an affluent area. The median household here earns $122,783 — 45% above the metro median of $84,833 — and per-capita income runs $52,733, both signals of concentrated wealth and high-earning professional households.

The population skews prime working age (median age 37.5) and family-oriented, with an average household of 2.7 people. With a diversity index of 44.3/100, 77573 is somewhat less diverse than the typical Houston ZIP. The largest groups are White (71.6%) and Hispanic or Latino (19.2%).

Put in context, 77573'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 — 49% of adults hold a bachelor's degree, versus the 35% metro average — reinforces the area's higher-skill, higher-earning profile.
