Start with the Campbellsville service area you actually want to measure
The Census record identifies Campbellsville city and its county relationship as Taylor County. It does not show how many people search for a lawyer, which matters they need or whether a particular channel performs well. That distinction matters when you configure attribution: a Campbellsville city page, a broader Taylor County page and a referral from outside the city should not automatically be treated as the same geographic opportunity. The useful question is not whether the population number predicts leads. It is whether your records can distinguish the location, practice area and source associated with each inquiry.
Recommended approach
Decide which geographic labels belong in your intake and reporting conventions. Review Campbellsville and Taylor County separately where that distinction affects service decisions, and avoid treating the population estimate as a forecast.
