1. Start with the geography your firm actually serves
Washington is recorded as a municipality in Tazewell County, Illinois. That relationship matters when you review attribution: a Washington inquiry and an inquiry from elsewhere in Tazewell County should not automatically be treated as the same local market. Population can establish that Washington is a defined place to include in a service-area review, but it cannot establish search demand, competition, case volume or revenue. Lead Attribution gives you a reason to keep those geographic distinctions visible in your records rather than collapsing every Illinois inquiry into one label.
Recommended approach
Decide which geographic fields your team needs when reviewing a lead: Washington city, Tazewell County, another Illinois location, or an unknown location. Confirm that the classification reflects the firm’s service area and intake policy. Then review whether the same source or landing page produces different outcomes by geography. Treat any apparent difference as a question for further review, not as proof that one place is more valuable.
