1. Start with Ontario’s actual service boundary
Your firm may describe its market as Ontario, Richland County, Ohio, or a wider area. Those labels are not interchangeable. The Census record identifies Ontario as a municipality and records its county relationship as Richland County. It does not show how many people call law firms, which practice areas they need, or whether callers are available at particular hours. Treat the population estimate as location and eligibility context, not as a forecast.
Recommended approach
Write down the geographic terms your callers use and the areas your firm accepts before configuring an answering path. In the consultation, ask how a caller from Ontario should be distinguished from an existing client, a caller outside the service area, or someone seeking a matter your firm does not handle. Keep the service-area decision separate from assumptions about demand.
