Start with the Marshall service area, not an invented market assumption
Marshall is a municipality in Missouri, and the recorded county relationship is Saline County. The 2020–2024 ACS five-year population estimate for Marshall city is 13,739, with a margin of error of 24. That figure describes the city population only. It does not establish legal demand, search behavior, competition, lead volume or revenue, and it does not describe all households or individuals your firm may serve. For custom software, the relevant local question is operational: which parts of your work involve people in Marshall, Saline County or elsewhere, and do those service boundaries change the workflow?
Recommended approach
Map the geographic fields your team actually uses. Decide whether a matter belongs to Marshall, Saline County or another service area; identify whether that value affects intake routing, reporting, communications or permissions; and keep the city, county and broader Missouri scope distinct. A local fact should shape data definitions, not become a performance claim.
