1. Start with the New Castle service area, not a population assumption
The relevant geography is New Castle city in Lawrence County, Pennsylvania. The Census record identifies New Castle as a municipality and places it in Lawrence County. Its population estimate can help define the area a firm may choose to examine, but it cannot establish how many people need legal help, how many firms compete for attention or how many inquiries reviews may produce. Those questions require firm-specific review and inquiry data.
Recommended approach
Define the reputation program around the places and legal services the firm actually serves. During an evaluation, separate New Castle city from the wider Lawrence County service area and record whether the Google Business Profile, website and review requests describe the same coverage. Do not treat a larger geographic label as evidence that the firm should solicit or advertise across it.
