1. Start with the geographic boundary you can actually serve
Bosseo describes Programmatic SEO as a system for dedicated pages for each legal service in each city within a selected footprint. Its public page says a firm can choose statewide coverage or limit the scope to selected counties. Bensville is recorded as a CDP in Charles County, Maryland, so it belongs in a Charles County review rather than being treated as a county or metropolitan area itself. The population estimate is eligibility evidence only. It cannot tell you whether people in Bensville search for a particular attorney, whether other firms compete for those searches, or whether a page would produce a qualified inquiry.
Recommended approach
Decide whether your firm serves Bensville alone, Charles County, or a broader Maryland footprint. Put that geographic decision in writing before discussing page counts. If your service area does not include Bensville or Charles County, do not create a page merely because the place appears in a geographic list.
