Start with Lilburn and Gwinnett County as separate geographic decisions
Lilburn’s recorded county relationship is Gwinnett County, but the city and county are not interchangeable for advertising purposes. Your firm may want to appear for people seeking help in Lilburn, people looking across Gwinnett County, or both. Those choices affect the service-area settings and the kinds of inquiries you may receive. Population is eligibility context only; it cannot tell you whether a particular legal category has enough demand or whether other firms are competing for it.
Recommended approach
List the locations your firm is genuinely prepared to serve, then compare that list with your preferred practice areas and intake capacity. Treat Lilburn, Gwinnett County and any broader Georgia geography as distinct review points. Do not expand coverage merely because a larger geography contains more residents.
