1. Start with Belleville’s actual service boundary
Belleville is a municipality in St. Clair County, Illinois. The 2020–2024 ACS five-year estimate records 41,370 residents, with a margin of error of 45. That is useful context when you define the geographic audience for a Belleville page, but it does not establish legal demand, search activity, lead volume or staffing needs. Your firm may serve Belleville, other parts of St. Clair County, or a wider Illinois area; those are decisions for your consultation and intake rules, not conclusions from population data.
Recommended approach
Write the intake around the geography your firm actually accepts. Decide whether location is an eligibility question, a routing question or simply information for staff review. If your service area extends beyond Belleville, make that boundary explicit in the opening experience so a visitor is not encouraged to complete an intake your firm cannot handle.
