1. Start with the right local boundary
the Census record identifies Fernandina Beach city as a municipality in Nassau County, Florida, with a 2020–2024 ACS 5-year population estimate of 13,420 and a margin of error of 27. A dashboard should preserve that distinction. Fernandina Beach, Nassau County, Florida and any neighboring market are not interchangeable cohorts. If your firm serves more than the city, combining every inquiry into one geographic total can obscure where a contact originated. The dashboard reference supports separating city cohorts and calls for separating Miami, Miami-Dade and neighboring city cohorts; for a Fernandina Beach firm, the same decision should be made deliberately for Fernandina Beach, Nassau County and any additional locations the firm chooses to measure.
Recommended approach
Ask for geographic reporting that keeps Fernandina Beach separate from Nassau County and from other selected service areas. Do not treat the Census population estimate as a forecast of leads or matters. Use it only as context while the firm validates its own inquiry and matter records.
