1. Treat Aberdeen’s geography as a reporting boundary
The U.S. Census Bureau records Aberdeen as a municipality in Brown County, South Dakota. Its 2020–2024 ACS five-year population estimate is 28,189, with a margin of error of 42. That figure describes the city population; it does not establish legal demand, search volume, lead volume, competition or revenue. It does provide a clear starting boundary for deciding how reports should distinguish Aberdeen from the rest of Brown County and from other South Dakota service areas.
Recommended approach
Ask whether your attribution views can separate Aberdeen, Brown County and broader South Dakota activity without treating them as interchangeable. Review landing pages, referral records and intake answers by the geographic area your firm actually serves. Keep households, individuals, the municipality and the county distinct when you interpret results.
