Start with the geography your firm actually serves
Plymouth is recorded as a municipality in Marshall County, Indiana. The 2020–2024 ACS five-year estimate lists 10,664 residents, with a margin of error of 41. That is context for defining a service area, not proof of legal demand, competition, search volume, lead volume or revenue. Your firm may serve Plymouth, other communities in Marshall County, or a wider Indiana market. Attribution should therefore preserve the difference between a Plymouth visit, a Marshall County inquiry and a broader Indiana matter rather than treating every contact as one local category.
Recommended approach
Before reviewing attribution, list the geographic labels your intake team already uses and decide which ones matter for reporting. Ask whether a lead record can be evaluated by service area, practice type and outcome without turning population into a forecast. Keep Plymouth and Marshall County distinct when that distinction affects staffing, follow-up or budget decisions.
