1. Start with the geographic question, not a guessed market size
The 2020–2024 ACS five-year population estimate is 12,989, with a margin of error of 26. The useful question is whether your records can distinguish a Newcastle inquiry from another service location and connect that inquiry to a measurable journey.
Recommended approach
Confirm which geographic labels matter to your practice, including Newcastle and the wider areas you intentionally serve. Then review whether those labels can be compared with source, landing page, intake answers and matter outcome without claiming that any location produces demand.
