Petrolia, TX population, income and ZIP codes

Petrolia city is a very small community in Texas, with 404 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #1341 of 1,863 ranked by population — larger than 28% of them. The median age here is 48.3 years against 39.1 nationally, a markedly older profile that usually tracks retirees staying put and younger households leaving for work. 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 Petrolia city earn a median of $51,771 a year, 34.1% below the national figure of $78,538 and 20% 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 15.8% of residents here, above the 12.4% national rate.

The typical owner-occupied home in Petrolia city is valued at $86,800, 71.4% below the national figure and 52% below the $179,100 peer median, while median gross rent runs $768 a month, 45.4% below the national figure, or roughly $9,216 across a full year. A household on the local median income would put about 17.8% 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 1.7×, 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. 79.3% 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.

With 404 residents, a handful of survey responses moves every median on this page. Compare Petrolia city against its county rather than against national figures.
