Start with Milan’s actual service footprint
The U.S. Census Bureau records Milan as a municipality in Rock Island County, Illinois, with a 2020–2024 ACS 5-year population estimate of 5,034 and a margin of error of 24.
Recommended approach
On a review call, define whether your intake serves Milan alone, Rock Island County, a wider Illinois area or another stated geography. Then identify which inquiry sources and matter types belong in the same workflow and which need separate routing.
