Trivoli, IL population, income and ZIP codes

Trivoli CDP is a very small community in Illinois, with 364 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #1027 of 1,462 ranked by population — larger than 29% of them. The median age here is 32.3 years against 39.1 nationally, a distinctly younger profile, typical of places with students, military posts or a fast-growing family population. 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 Trivoli CDP earn a median of $66,766 a year, 15% below the national figure of $78,538 and 10% below the $74,244 median for the 698 Illinois 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 3.6% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Trivoli CDP is valued at $155,300, 48.8% below the national figure and 13% below the $179,100 peer median, while median gross rent runs not published a month. The home-price-to-income ratio works out to 2.3×, 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. 90.2% 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.

With 364 residents, a handful of survey responses moves every median on this page. Compare Trivoli CDP against its county rather than against national figures.

The Census withheld gross rent for Trivoli CDP because the sample was too thin to publish at this geography. Those values were suppressed at the source, not lost in our dataset, and we do not model a replacement. Everything else on this page comes straight from the ACS 2019-2023 ACS 5-year tables.
