Westmont village, IL in context
How this area compares with national benchmarks.
Westmont village is a mid-size town in Illinois, with 24,201 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #94 of 1,462 ranked by population — larger than 93% of them. The median age here is 42.5 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 Westmont village earn a median of $83,622 a year, 6.5% above the national figure of $78,538 and 13% 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 11.4% of residents here, below the 12.4% national rate.
The typical owner-occupied home in Westmont village is valued at $369,100, 21.7% above the national figure and 106% above the $179,100 peer median, while median gross rent runs $1,427 a month, 1.5% above the national figure, or roughly $17,124 across a full year. A household on the local median income would put about 20.5% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is within the standard affordability guideline. The home-price-to-income ratio works out to 4.4×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 54.9% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.
