1. Start with the geographic question, not the population number
DeKalb is recorded as a municipality in DeKalb County. The 2020–2024 ACS five-year estimate records 40,443 residents, with a margin of error of 215. That is context for defining a service area; it does not establish legal demand, review volume, competition, search behavior or likely revenue. Your firm may serve the city, the county, Illinois more broadly, or a narrower set of communities. Those are different scopes and should not be combined casually.
Recommended approach
Write down the places and matter types the firm is prepared to serve before assessing its review profile. During a Bosseo consultation, compare that intended coverage with the geographic wording used in your Google Business Profile, website and review requests. Ask whether the proposed program should focus on DeKalb city, DeKalb County, or another exact service boundary. Measure inquiries by location only if the firm records that information consistently.
