1. Define the Jefferson City footprint before counting pages
The U.S. Census Bureau records Jefferson City city as a municipality in Missouri. Its 2020–2024 ACS 5-year population estimate is 42,488, with a margin of error of 65. The recorded county relationships are Callaway County and Cole County. That information can help you identify a geographic starting point, but it does not establish search demand, competition, legal need, leads or revenue. Bosseo’s public programmatic SEO page says a firm can choose statewide coverage or limit the work to selected counties. For your firm, that makes geographic eligibility a business decision rather than a population-based forecast.
Recommended approach
Decide whether Jefferson City is the primary municipality, whether Callaway County and Cole County are both within your actual service area, and whether any additional Missouri counties should be considered. Ask Bosseo to show how each choice changes the proposed service-and-city set. Do not approve pages for places your firm does not intend to serve.
