Duncanville city, TX in context

How this area compares with national benchmarks.

Duncanville city is a small city in Texas, with 39,879 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #91 of 1,863 ranked by population — larger than 95% of them. The median age here is 37.2 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 Duncanville city earn a median of $71,381 a year, 9.1% below the national figure of $78,538 and 10% 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 9.9% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Duncanville city is valued at $239,200, 21.2% below the national figure and 34% above the $179,100 peer median, while median gross rent runs $1,562 a month, 11.1% above the national figure, or roughly $18,744 across a full year. A household on the local median income would put about 26.3% 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. 65.3% 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.

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.
