1. Define Centreville coverage without treating geography as demand
Centreville CDP is recorded in Fairfax County, Virginia. Your firm may serve Centreville specifically, nearby Fairfax County communities, or a broader Virginia area; those are different geographic choices and should not be blended casually. Bosseo’s LSA page describes category and geography targeting, including practice-area categories and service areas. That makes geographic scope an implementation decision: determine which locations your firm actually accepts, which locations are outside its preferred service area, and whether a call from elsewhere in Virginia should be handled differently. The Centreville population estimate is useful context for the size of the named place, but it cannot show how many people search for a lawyer or how many inquiries your firm will receive.
Recommended approach
Bring a precise service-area map and an out-of-area policy to the consultation. Ask which Centreville and Fairfax County areas should be included, how location fit will be reviewed, and what happens when an inquiry falls outside the firm’s intended geography.
