Overview
Understanding ZIP code 77450
ZIP code 77450 is assigned to Katy, TX, and falls within Harris County. Like every US postal code, it began as a mail-routing device rather than a geographic boundary — the US Postal Service groups delivery routes under a single code so carriers and sorting equipment can process mail efficiently. Today it also serves as a practical shorthand for the area itself: roughly 73,226 people live inside it.
At 3,722 residents per square mile spread over 19.676 square miles, 77450 reads as a densely built-up area. It is one of the more heavily populated postal codes in the country, and density shapes almost everything else on this page — how people get to work, whether they own or rent, and what housing costs.
Household earnings run above the national median. At $105,607, 77450 sits comfortably in the upper half, ahead of 86% of them. The US median for comparison is $70,109. Bear in mind that median income describes the midpoint household, not the average — it is not pulled upward by a handful of very high earners the way a mean would be.
Living here
What life in Katy looks like
Housing in 77450 costs well above the national median. A typical home is valued at $342,000 against a US median of $207,500, and median gross rent runs $1,730 a month. The split between owning and renting is fairly even at 69.6% owner-occupied, which tends to indicate a mix of housing types rather than one dominant form.
The building stock is dominated by detached single-family houses, which account for 76.5% of housing units here. The median construction year is 1995, making the housing here from the later twentieth century. At 3.6%, vacancy is low — housing here is tightly held.
The population skews broadly in line with the national age profile, with a median age of 37.6 against 42 nationally. The average household holds 2.89 people, and 80.3% are family households.
Getting to work takes 33.7 minutes on average one way. The dominant mode is drove alone at 72.4% of workers, while 16.0% work from home. Commute patterns are one of the better proxies for how a place actually functions day to day.
Where to stay
Where to stay in Katy, TX
Katy is a built-up area, so you will generally find a mix of chain hotels near the main approach roads and a smaller number of independent properties closer to the centre. Staying in 77450 itself often costs less than an equivalent room in the nearest downtown while keeping you close to it.

Practical uses
What ZIP code 77450 is used for
Beyond addressing mail, 77450 does a lot of quiet administrative work. Retailers use it to calculate shipping and sales tax at checkout. Insurers use it to set premiums, since risk profiles vary geographically. Employers and marketers use it to define service areas. Government agencies use it to route benefits and organise reporting. If you have ever been asked for a postal code by a form that clearly does not intend to send you anything, this is why.
For anyone weighing a move, 77450 offers a compact profile of Katy: 73,226 residents, a median household income of $105,607, 52.6% of adults holding a bachelor's degree or higher, and an unemployment rate of 4.5%. A handful of figures like these answer more relocation questions than most neighbourhood guides do.
One caution worth repeating: a postal code is not a neighbourhood. 77450 may cover parts of several distinct areas, and a single neighbourhood in Katy may be split across more than one code. Boundaries also shift as USPS adjusts delivery routes. Treat the figures here as describing a delivery area, which is what they actually measure.
