Sullivan City, TX population, income and ZIP codes

Sullivan City city is a small town in Texas, with 3,919 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #492 of 1,863 ranked by population — larger than 73% of them. The median age here is 36.1 years against 39.1 nationally, a slightly younger profile than the country as a whole. At this population the ACS sample is small, so the margin of error around every dollar figure below is wide — treat the numbers as a band, not a point, and expect them to move between annual releases without the place itself changing.

Households in Sullivan City city earn a median of $44,286 a year, 43.6% below the national figure of $78,538 and 32% 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 29.9% of residents here, well above the 12.4% national rate, which is the single clearest signal in this dataset that median income here is carried by a narrow band of households.

The typical owner-occupied home in Sullivan City city is valued at $90,800, 70.1% below the national figure and 49% below the $179,100 peer median, while median gross rent runs $618 a month, 56% below the national figure, or roughly $7,416 across a full year. A household on the local median income would put about 16.7% 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 2.1×, against roughly 3.9× nationally, so purchase prices are unusually low against local pay, the pattern in places where supply is plentiful and wage growth has been flat. 90.3% of occupied homes are owner-occupied versus 65% nationally, an owner-dominated market where rental listings are scarce and rent medians rest on a thin sample. 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.

Every value on this page is published directly by the Census for this area — nothing is modelled or interpolated. 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.
