1. Start with the geography your firm actually serves
The U.S. Census Bureau records Ypsilanti charter township as a municipal-town in Washtenaw County, Michigan, with a 2020–2024 ACS five-year population estimate of 55,066 and a margin of error of 50. That is geographic context, not evidence of legal demand, lead volume, competition or revenue. It should therefore change the attribution question rather than become a marketing claim. First decide whether your records distinguish Ypsilanti from other Washtenaw County locations and from broader Michigan activity. If they do not, a report labelled “Ypsilanti” may combine different service areas and make budget decisions harder.
Recommended approach
Define the geographic labels your firm will review before interpreting results. Ask whether a Ypsilanti landing page, a county-level page, a referral, an advertisement or a direct visit should be treated as distinct source context. Review the boundary and service-area definitions with Bosseo rather than assuming that population geography equals client geography.
