Johnsburg, IL population, income and ZIP codes

Johnsburg village is a mid-size town in Illinois, with 6,374 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #296 of 1,462 ranked by population — larger than 79% of them. The median age here is 41.3 years against 39.1 nationally, a slightly older profile than the country as a whole. Places under 65,000 residents only appear in the five-year release, never the one-year file, so these values pool sixty months of responses and lag the current year by design.

Households in Johnsburg village earn a median of $106,827 a year, 36% above the national figure of $78,538 and 44% above 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 11.9% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Johnsburg village is valued at $312,200, 2.9% above the national figure and 74% above the $179,100 peer median, while median gross rent runs $1,330 a month, 5.4% below the national figure, or roughly $15,960 across a full year. A household on the local median income would put about 14.9% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is cheap relative to what people here earn. The home-price-to-income ratio works out to 2.9×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 88.4% 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.
