1. Start with Warren coverage, not assumptions about demand
Your service area is Warren, Michigan, within Macomb County. The Census population estimate describes the city as a municipality and records 137,928 residents for the 2020–2024 ACS 5-year period. It does not show how many people call law firms, which practice areas they need, when they call, or whether they would retain counsel. For that reason, population should inform the scope of your review rather than serve as a forecast. Ask which phone numbers serve Warren callers, whether your firm also accepts matters elsewhere in Macomb County, and whether the same intake path should apply across those geographies.
Recommended approach
Map your actual service boundaries and compare them with the locations, practice areas and consultation rules your callers hear. Keep Warren and Macomb County distinct in your internal reporting so a city-level observation does not become a county-wide demand claim.
