1. Start with the geographic record, not a demand assumption
The available Census record identifies Waterloo as a municipality in Monroe County and records a 2020–2024 ACS 5-year population estimate of 11,129. That is eligibility and geographic context only. It cannot tell you how many people search for legal services, which practice areas they need, how many firms compete for attention or how many inquiries your firm may receive. For attribution, the relevant question is whether your reporting can distinguish activity associated with Waterloo from activity elsewhere in Monroe County, Illinois or another service area. A location label should not be treated as proof that a page, advertisement or referral produced a case.
Recommended approach
Define the geographic fields your firm actually needs before reviewing performance. Decide whether reporting should separate Waterloo from Monroe County and from other places your firm serves. Keep those categories distinct from the individual, household and municipality concepts used in demographic data. Then inspect whether your current records preserve the location context needed for a meaningful channel or case-type review.
