1. Start with the South Park geography you actually serve
The 2020–2024 ACS five-year population estimate is 13,706, with a margin of error of 25. For attribution, the useful question is narrower: when your firm identifies a South Park inquiry, can you connect that inquiry to the marketing journey and the legal-service information the person provided?
Recommended approach
Define the geographic labels your firm will use before reviewing attribution. Keep South Park, Allegheny County, Pennsylvania and any broader service area as distinct fields or reporting views. Instead, decide whether location should be reviewed alongside practice area, qualification status, consultation status and signed-case status.
