Olivet, IL population, income and ZIP codes

Olivet CDP is a very small community in Illinois, with 156 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #1263 of 1,462 ranked by population — larger than 13% of them. The median age here is 37.5 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 Olivet CDP earn a median of not published a year. 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 14.9% of residents here, above the 12.4% national rate.

The typical owner-occupied home in Olivet CDP is valued at $129,500, 57.3% below the national figure and 28% below the $179,100 peer median, while median gross rent runs not published a month. 75% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. 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.

The Census withheld household income, gross rent for Olivet 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.
