Katy city, TX in context

How this area compares with national benchmarks.

Katy city is a mid-size town in Texas, with 23,900 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #142 of 1,863 ranked by population — larger than 92% of them. The median age here is 36 years against 39.1 nationally, a slightly younger profile than the country as a whole. Places under 65,000 residents only appear in the five-year release, never the one-year file, so these values pool sixty months of responses and lag the current year by design.

Households in Katy city earn a median of $107,332 a year, 36.7% above the national figure of $78,538 and 66% above the $64,654 median for the 1,008 Texas cities we cover. The median is the midpoint household, not an average, so a handful of very high earners cannot drag it upward the way they distort a mean. Poverty reaches 5.4% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Katy city is valued at $376,800, 24.2% above the national figure and 110% above the $179,100 peer median, while median gross rent runs $1,609 a month, 14.4% above the national figure, or roughly $19,308 across a full year. A household on the local median income would put about 18% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is cheap relative to what people here earn. The home-price-to-income ratio works out to 3.5×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 77.2% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.
