Carol Stream, IL population, income and ZIP codes

Carol Stream village is a small city in Illinois, with 39,427 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #42 of 1,462 ranked by population — larger than 97% of them. The median age here is 39.3 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 Carol Stream village earn a median of $105,395 a year, 34.2% above the national figure of $78,538 and 42% 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 7% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Carol Stream village is valued at $308,700, 1.7% above the national figure and 72% above the $179,100 peer median, while median gross rent runs $1,465 a month, 4.2% above the national figure, or roughly $17,580 across a full year. A household on the local median income would put about 16.7% 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. 68.1% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.
