Darien city, IL in context

How this area compares with national benchmarks.

Darien city is a mid-size town in Illinois, with 21,855 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #110 of 1,462 ranked by population — larger than 92% of them. The median age here is 44.8 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.

This figure covers the household, not the worker: two people on ordinary wages at one address outrank a single professional in the same table.
