1. Start with the geographic question your records can actually answer
Northbrook village is a municipality in Cook County, Illinois. The 2020–2024 ACS five-year estimate records 34,585 residents, with a margin of error of 223. That figure is context, not evidence of legal demand, search activity, competition, inquiries or signed matters. It should not become a substitute for attribution. The practical question is narrower: when an inquiry is associated with Northbrook, can your firm identify how that person reached you, what they asked about and what happened next?
Recommended approach
Keep Northbrook as a service-area and reporting dimension, not as a forecast. During review, define how your firm records geography, practice area, source and outcome. Then test whether those fields can be joined to the digital journey without treating population as a lead estimate.
