Heritage Lake, IL population, income and ZIP codes

Heritage Lake CDP is a small town in Illinois, with 1,708 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #541 of 1,462 ranked by population — larger than 63% of them. The median age here is 40.3 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 Heritage Lake CDP earn a median of $117,422 a year, 49.5% above the national figure of $78,538 and 58% 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 10.2% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Heritage Lake CDP is valued at $210,600, 30.6% below the national figure and 18% above the $179,100 peer median, while median gross rent runs not published a month. The home-price-to-income ratio works out to 1.8×, 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. 97.4% 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. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

The Census withheld gross rent for Heritage Lake 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.
