1. Start with the geography you actually serve
The U.S. Census Bureau records St. Louis as a municipality in Gratiot County, Michigan, with a 2020–2024 ACS five-year population estimate of 7,367 and a margin of error of 18. That is a description of the municipality, not evidence of search demand, case demand or likely lead volume. Attribution is useful here because it can preserve the landing page, channel and referral path associated with each inquiry.
Recommended approach
Define the geographic labels your intake team will use, then review whether each inquiry can be connected to a source journey and an outcome. Keep municipality, county, metropolitan area, household and individual distinctions separate in your reporting.
