1. Start with St. Louis city’s actual service boundary
The U.S. Census Bureau records St. Louis city as a municipality in Missouri, with a 2020–2024 ACS five-year population estimate of 288,512. The corresponding county relationship is St. Louis city. That fact describes the geography and population record; it does not establish call demand, legal need, competition or staffing requirements. Your firm should therefore define whether this page and its answering workflow serve St. Louis city only or also other places in the metropolitan area. A city boundary, a county relationship and a broader metro service area are not interchangeable.
Recommended approach
Before configuring call handling, write down the geographic scope your firm actually accepts. Use that scope when deciding which callers are relevant, which practical questions the system may answer and when a call should go to a person. Do not use the population figure as a forecast. Use your own phone records and consultation data to decide whether after-hours coverage or overflow protection deserves priority.
