1. Start with the actual St. Joseph geography
The U.S. Census Bureau records St. Joseph charter township as a municipal-town in Berrien County, Michigan. Its 2020–2024 ACS five-year population estimate is 9,879, with a margin of error of 41. That figure describes the population estimate for the named Census geography. It does not establish legal-search demand, competition, case volume, or revenue. It also should not be treated as a substitute for a service-area decision. A firm may serve St. Joseph, other parts of Berrien County, or a broader Michigan footprint, but those are separate choices.
Recommended approach
Use St. Joseph as one geographic input, not as a demand forecast. During evaluation, list the communities and counties where the firm is prepared to accept matters, distinguish them from places it merely wants visibility, and decide whether a county-limited footprint is more appropriate than statewide coverage.
