1. Start with the Mendota service area, not a presumed demand signal
The Census records Mendota city as a municipality in LaSalle County. Its 2020–2024 ACS five-year population estimate is 6,994, with a margin of error of 293. That fact can help define the location in your reporting, but it cannot tell you how many people seek legal help, which practice areas they need, how many firms compete for attention or how many inquiries a channel will produce. A useful attribution design should therefore distinguish Mendota from the broader county and from any other Illinois geography your firm serves. Do not treat households, individuals, municipalities and counties as interchangeable reporting categories.
Recommended approach
Ask Bosseo to show how location is represented in a lead record and dashboard. Decide whether your firm needs Mendota and LaSalle County separated, and document any additional service areas before interpreting channel or case-type results.
