1. Set the local boundary before you design the intake
Elmhurst is recorded as a city in Illinois, with relationships to both Cook County and DuPage County. The 2020–2024 ACS five-year estimate records 45,671 residents, with a margin of error of 45. That is geographic and population context, not proof of legal demand, search volume, case volume or staffing requirements. It should not determine how many inquiries your firm expects or what languages visitors use. It can, however, help you define the service area that appears in your intake questions and routing decisions. If your firm serves Elmhurst plus selected locations in Cook County, DuPage County or elsewhere in Illinois, decide those boundaries explicitly rather than allowing a visitor’s location to be interpreted informally.
Recommended approach
Start by listing the locations your firm accepts, declines or sends elsewhere. Review whether an Elmhurst visitor should enter a county, municipality, ZIP code or another location detail for the practice area. Keep the geography limited to what your lawyers use when deciding whether to review a matter. Measure the number of inquiries that cannot be assigned confidently, rather than treating Elmhurst’s population as a forecast.
