1. Start with the Mahomet geography you actually want to measure
The U.S. Census Bureau records Mahomet as a municipality in Champaign County. For a law firm, that distinction matters because a dashboard can become misleading when a local place, county-wide service area and broader Illinois coverage are treated as one market. A Mahomet inquiry may be relevant even if the caller is elsewhere in Champaign County, while a county-wide result should not automatically be presented as Mahomet performance. Population is context only; it cannot prove that residents need a particular legal service or that marketing will produce matters.
Recommended approach
Before reviewing any performance view, decide which geographic labels your firm needs: Mahomet, Champaign County, another service area or Illinois. Ask how each label would appear in rankings, lead records, calls and attribution. Require the dashboard review to distinguish a measured geographic field from an interpretation about market opportunity.
