1. Start with Seabrook’s actual service area—not a population assumption
Seabrook is recorded as a municipal town in Rockingham County, New Hampshire. The 2020–2024 ACS five-year population estimate is 8,427, with a margin of error of 18.
Recommended approach
Bring a recent view of your phone activity to the consultation if you have one. Review calls by time, disposition and practice area, and separate Seabrook callers from other Rockingham County or New Hampshire callers only if your records support that distinction. If you do not track those fields, identify that as a measurement gap rather than filling it with an estimate.
