1. Start with the geographic relationship, not a population assumption
Lake Holiday is a CDP in LaSalle County. That is a precise geographic relationship, but it does not by itself define your service area or prove that a Lake Holiday visitor will contact your firm. Your attribution review should therefore distinguish the location a visitor is considering from the location your firm serves, the matter type they select and the path they take before contacting you. Keep Lake Holiday records separate from broader LaSalle County activity when that distinction matters to a budget or intake decision.
Recommended approach
Agree on the geographic fields and reporting questions you actually need before judging performance. Review whether Lake Holiday should be treated as its own location, grouped with LaSalle County, or handled within a broader Illinois service area. Do not use the Census population estimate as a forecast of inquiries.
