1. Start with the geography you actually serve
The 2020–2024 ACS five-year population estimate is 11,313, with a margin of error of 1,099. The useful attribution question is narrower: when people within the firm’s service area contact the firm, can the firm identify the path that preceded the inquiry and what happened afterward?
Recommended approach
Define the service area and intake scope before reviewing attribution. Keep Linthicum, Anne Arundel County and any broader Maryland or metropolitan coverage distinct in reporting.
