1. Start with the Buffalo Grove service area, not a population forecast
Buffalo Grove is recorded as a municipality in Cook County and Lake County. That exact relationship matters when you decide how an inquiry is classified, assigned or reported. A firm may serve Buffalo Grove across county boundaries, but the Census population estimate does not show how many people need legal help, how many contact a law firm, or how many become matters. Automation should therefore preserve the geographic information your firm actually collects instead of turning a place name into an unsupported demand signal.
Recommended approach
Review whether Buffalo Grove is captured consistently in your forms, call notes, intake answers and CRM records. Decide whether county, municipality, service area and matter type should be separate fields. Then determine whether those fields should influence routing, reporting or follow-up. Keep any geographic rule tied to a documented business decision, not an assumption about residents.
