1. Start with the Springfield and Calhoun County boundary
The U.S. Census Bureau records Springfield as a Michigan municipality in Calhoun County. Its 2020–2024 ACS five-year population estimate is 5,269, with a margin of error of 22. That is geographic eligibility evidence, not evidence of legal demand, search volume, competition, leads or revenue. For an ROI Dashboard, the distinction matters: a firm should decide whether a report is meant to describe Springfield city, Calhoun County, a broader Michigan service area, or another defined geography. Mixing those levels can make a local number appear more specific than it is.
Recommended approach
Before reviewing performance, ask Bosseo to show how geography is represented in the proposed dashboard and how you would distinguish Springfield from Calhoun County and any wider territory. Treat a city, county, metropolitan area, Michigan-wide view, household and individual as different reporting concepts unless the dashboard explicitly defines them.
