1. Start with the geographic question your records can answer
Merrillville is a municipality in Lake County, Indiana. The 2020–2024 ACS five-year estimate records 36,476 residents, with a margin of error of 80. That figure describes population eligibility only; it does not establish legal demand, search behavior, competition, language preference, staffing needs, lead volume, or revenue. Attribution therefore should not treat Merrillville’s population as a forecast. It should help you examine the actual journeys associated with the geographic areas and services your firm chooses to serve.
Recommended approach
Define the geographic labels you want to review before judging performance. Keep Merrillville, Lake County, broader Indiana service areas, and any metropolitan area as separate concepts. Ask whether a record identifies a location through an intake answer, a landing page, a referral, or another reliable field rather than treating a place name as proof of client origin.
