Dorchester, IL population, income and ZIP codes

Dorchester village is a very small community in Illinois, with 185 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #1228 of 1,462 ranked by population — larger than 16% of them. The median age here is 42.8 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 Dorchester village earn a median of $121,250 a year, 54.4% above the national figure of $78,538 and 63% above 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 1.1% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Dorchester village is valued at $133,300, 56.1% below the national figure and 26% below the $179,100 peer median, while median gross rent runs not published a month. The home-price-to-income ratio works out to 1.1×, 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. 100% 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. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.

With 185 residents, a handful of survey responses moves every median on this page. Compare Dorchester village against its county rather than against national figures.

The Census withheld gross rent for Dorchester 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.
