1. Start with Cary’s exact service area, not a demand assumption
The 2020–2024 ACS 5-year population estimate is 17,923, with a margin of error of 48. The distinction matters when you evaluate a phone system. A firm serving Cary may also define its service area beyond the village, but that broader geography should be stated by the firm rather than inferred from the municipal record.
Recommended approach
Use Cary and McHenry County as explicit geographic labels in the firm profile only where they reflect the firm’s actual service area. During a consultation, review which callers the system should treat as potential new clients, current clients or other inquiries, and decide whether location is a qualification question, an informational response or a matter for attorney review.
