1. Start with Harrisburg’s actual service area
The relevant local boundary should be decided before attribution is interpreted. Harrisburg city is recorded in Dauphin County, and the cited Census estimate covers the municipality—not every household or individual who may contact a law firm from the surrounding county or wider Pennsylvania market. A population estimate can establish the place being evaluated, but it cannot show how many people need legal help or which channels they use.
Recommended approach
Define the geographic labels your firm wants to review separately: Harrisburg city, Dauphin County, other Pennsylvania locations, and any broader service area the firm intentionally serves. Then decide whether each inquiry should be classified by the visitor’s stated location, the landing page viewed, the office or practice area selected, or another firm-approved rule. Do not use the city’s population as a proxy for demand or expected lead volume.
