Kirby city, TX in context

How this area compares with national benchmarks.

Kirby city is a mid-size town in Texas, with 8,100 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #311 of 1,863 ranked by population — larger than 83% of them. The median age here is 39.1 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 Kirby city earn a median of $58,700 a year, 25.3% below the national figure of $78,538 and 9% below 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 9.6% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Kirby city is valued at $159,000, 47.6% below the national figure and 11% below the $179,100 peer median, while median gross rent runs $1,114 a month, 20.8% below the national figure, or roughly $13,368 across a full year. A household on the local median income would put about 22.8% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is within the standard affordability guideline. The home-price-to-income ratio works out to 2.7×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 70.4% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. Rent is reported gross — contract rent plus tenant-paid utilities — which is why it runs above the advertised price on a listing for the same unit.

All values below were released by the Census for this exact geography, with no gap-filling on our side. Small-area estimates still carry wider margins of error than state or national figures, so check the linked ACS tables before relying on them for lending, appraisal or legal work.
