Start with Meridian’s actual service geography
The 2020–2024 ACS five-year population estimate is 44,217, with a margin of error of 56. The useful attribution question is narrower: when a person your firm serves contacts you, can the record distinguish a Meridian-related journey from activity elsewhere in Ingham County or Michigan?
Recommended approach
Define the geographic fields your team will use before reviewing performance. Decide whether reports should separate Meridian, the wider Ingham County service area, metropolitan activity and statewide inquiries. Use it only to make the service boundary explicit and to keep local reporting from blending unlike geographies.
