Start with the geography you actually serve
Lombard is a municipality in DuPage County, Illinois. The 2020–2024 ACS five-year estimate records 43,619 residents, with a margin of error of 334. That is a description of the place, not evidence of legal demand, search volume, competition or likely case volume. For attribution, the geographic fact matters because your reporting should distinguish Lombard inquiries from the broader DuPage County territory your firm may serve. A single “local lead” label can hide whether a page, referral or advertisement is producing inquiries from the place you are evaluating or from elsewhere in the county.
Recommended approach
Before reviewing performance, agree on the geographic fields that matter to your firm: Lombard, other DuPage County communities, and locations outside the intended service area. Use those fields to interpret source and outcome records, not to assume that any population figure predicts results.
