Population and Growth
The incorporated City of Katy itself has a population of about 25,000, but when people say “Katy,” they usually mean the much larger Katy ISD area that spreads across three counties.
It is extremely challenging to get accurate population statistics and demographics for the Katy Area…since it is not all incorporated. According to the Katy Area Economic Development Council’s Website (https://www.katyedc.org/quality-of-life/education)
Depending on how you measure it, the greater Katy area is home to 300,000 to 400,000 residents—and growing rapidly. This distinction matters because if you only look at city limits, you’ll miss the scale of the suburban boom.

Note the green portion is what we refer to as “Katy TX” and is covered by Katy ISD and mostly has Katy addresses, but the red portion is what is “incorporated” as the City of Katy and we call “Old Katy.”
Demographics
Katy growth means diversity. You’ll meet people from all over the United States who’ve relocated for work, as well as international families who are drawn by Katy’s schools and opportunities. The cultural mix has given rise to a wide variety of restaurants, community organizations, and events that make Katy feel both cosmopolitan and deeply Texan at the same time.
