1. Start with the Wheeling service area, not a population assumption
A firm serving Wheeling may receive inquiries connected to more than one county relationship because the village is recorded in Cook County and Lake County. That geographic fact can affect how you define service-area routing, reporting labels and matter-review questions. It does not establish that a particular practice area is in demand or that a particular response path is required.
Recommended approach
On a consultation, identify which geographic information your firm actually needs at intake. Decide whether it should be recorded as an answer, used for routing, reviewed by staff or retained only for reporting. Keep geographic fields separate from eligibility, conflict, urgency and legal-issue questions.
