Killeen, TX population, income and ZIP codes

Killeen city is a mid-size city in Texas, with 156,144 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #19 of 1,863 ranked by population — larger than 99% of them. The median age here is 30 years against 39.1 nationally, a distinctly younger profile, typical of places with students, military posts or a fast-growing family population. At this size the Census also publishes one-year estimates; the five-year values used here are steadier and let you compare against smaller neighbours on the same basis.

Households in Killeen city earn a median of $58,339 a year, 25.7% below the national figure of $78,538 and 10% below the $64,654 median for the 1,008 Texas cities we cover. Median household income counts every pre-tax dollar arriving at an address — wages, self-employment, Social Security, pensions, interest and public assistance — for everyone living there, so multi-earner households pull the figure up even where individual pay is modest. Poverty reaches 17.2% of residents here, above the 12.4% national rate.

The typical owner-occupied home in Killeen city is valued at $196,000, 35.4% below the national figure and 9% above the $179,100 peer median, while median gross rent runs $1,147 a month, 18.4% below the national figure, or roughly $13,764 across a full year. A household on the local median income would put about 23.6% 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 3.4×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 48.6% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. 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.

A median age of 30 means a large student or early-career population; income medians in places like this understate household resources, since many residents are supported from outside the address.
