Start with the geographic question your firm actually needs to answer
Gaithersburg city is recorded in Montgomery County, Maryland. A firm may serve the city, the wider county, or another defined service area, but the Census record does not establish where prospective clients search, which matters they need, or which channels reach them. Attribution therefore should not begin with an assumption that population equals opportunity. It should begin with a review of the geographic labels your firm uses in its marketing and intake records. If your website includes Gaithersburg pages, county pages or broader Maryland coverage, the useful question is whether the journey record identifies the landing page and subsequent outcome—not whether a population estimate can predict results.
Recommended approach
In a consultation, define the geographic scope you want to compare. Ask which landing pages, channels and case types should be reviewed together, and which should remain separate. Keep Gaithersburg, Montgomery County and Maryland as distinct reporting contexts unless your firm deliberately treats them as one service area.
