1. Define the market boundary before judging a source
The 2020–2024 ACS five-year population estimate is 11,591, with a margin of error of 744. Your attribution review should therefore distinguish inquiries associated with Garden City from matters elsewhere in Horry County, the wider South Carolina market or another service area. A report that combines those geographies may make a channel appear more or less useful than it is for the clients you intend to serve.
Recommended approach
Agree on the geographic labels your team will use before reviewing performance. Ask whether a record identifies Garden City specifically, another Horry County community, or only South Carolina.
