1. Start with the geographic boundary that your records actually use
Brigham City is recorded as a municipality in Box Elder County. That relationship matters when you review landing pages, referral descriptions and matter records: “Brigham City” and “Box Elder County” are not interchangeable labels, and neither should be treated as proof of a wider service area. Population is eligibility evidence only. It cannot tell you how many people search for a lawyer, which practice areas they need, or whether a particular channel produces cases. Attribution can help you compare the geographic wording attached to a journey with the page, channel and eventual outcome. That makes the city-versus-county distinction a measurement question rather than a reason to assume demand.
Recommended approach
Decide which geographic labels your firm wants to report separately. Then review whether each inquiry is tied to the landing page, intake answers and matter outcome needed for that comparison. Do not use the ACS population estimate as a forecast.
