1. Start with the geography your firm actually serves
The 2020–2024 ACS five-year population estimate is 26,970, with a margin of error of 31. That is context for defining a service area, not evidence of legal demand, competition, call volume or future revenue. A firm may serve Horsham alone, Montgomery County more broadly, or clients from outside both areas. Attribution should preserve those distinctions instead of treating every inquiry as interchangeable.
Recommended approach
In a consultation, define the geographic labels your team actually uses for intake and reporting: Horsham, Montgomery County, Pennsylvania, and any additional service areas the firm chooses to evaluate. This keeps local planning precise while leaving demand and conversion questions to the firm’s own data.
