1. Start with the geography your firm actually serves
The U.S. Census Bureau records Northville township as a municipal-town in Wayne County, Michigan, with a 2020–2024 ACS 5-year population estimate of 31,557 and a margin of error of 72. That is geographic and eligibility context, not evidence of search demand, legal need, competition, calls or case volume. Attribution should therefore preserve the location associated with an inquiry without treating the population figure as a forecast. Ask whether your records distinguish Northville township from other places your firm serves, and whether a location is captured as part of the inquiry rather than guessed later from a phone number or memory.
Recommended approach
Define the geographic fields you need before reviewing performance. Decide whether Northville is a service area, an office location, a landing-page location or simply one part of a broader Wayne County coverage plan. Then test whether those distinctions remain visible when a lead changes channels or returns later.
