Start with the geographic relationship, not a population assumption
Rose Hill CDP is recorded in Fairfax County, Virginia. A firm may serve people in Rose Hill, elsewhere in Fairfax County, or beyond it, and those areas should not be treated as interchangeable. The Census population estimate describes residents of the CDP; it does not identify households with legal needs or people searching for a particular practice area. Attribution therefore matters because it can separate the location a page addresses from the path an individual inquiry actually took. The Bosseo page describes channel, referrer, landing page, device and session detail as part of a lead journey.
Recommended approach
Before judging performance, define the geographic scope you want to evaluate: Rose Hill specifically, Fairfax County more broadly, or both as separate views. Ask whether your records preserve the landing page, source and case information needed to distinguish those scopes. Do not use the population estimate as a forecast. Use observed inquiry and matter data to decide whether geographic pages, campaigns or referrals warrant further attention.
