Marietta, IL population, income and ZIP codes

Marietta village is a very small community in Illinois, with 110 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #1328 of 1,462 ranked by population — larger than 9% of them. The median age here is 39.5 years against 39.1 nationally, a slightly older 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 Marietta village earn a median of $57,188 a year, 27.2% below the national figure of $78,538 and 23% below the $74,244 median for the 698 Illinois 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 13.6% of residents here, above the 12.4% national rate.

The typical owner-occupied home in Marietta village is valued at $81,700, 73.1% below the national figure and 54% below the $179,100 peer median, while median gross rent runs not published a month. The home-price-to-income ratio works out to 1.4×, 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. 97.9% 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 110 residents, a handful of survey responses moves every median on this page. Compare Marietta village against its county rather than against national figures.

The Census withheld gross rent for Marietta village 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.
