Start with the geography your website actually serves
The U.S. Census Bureau records Jefferson City city as a municipality in Missouri, with county relationships to Callaway County and Cole County. Its 2020–2024 ACS 5-year population estimate is 42,488, with a margin of error of 65. That figure describes the municipality; it does not establish legal demand, search volume, competition, lead volume or revenue. For hosting, the useful implication is narrower: your website may need to support visitors from Jefferson City as well as people considering a firm that serves one or both named counties. Those audiences may arrive on different practice-area, location or contact pages, so review the actual site structure and traffic patterns rather than choosing infrastructure from population alone.
Recommended approach
Define the geographic scope of your site before the technical review. Identify which pages serve Jefferson City, Callaway County and Cole County, then ask whether the current host handles those pages, forms and assets consistently. Treat the Census geography as a boundary for planning—not proof that any particular service page will attract visitors.
