1. Start with St. Marys and Camden County as separate reporting dimensions
The U.S. Census Bureau records St. Marys as a municipality in Camden County, Georgia. Its 2020–2024 ACS 5-year population estimate is 19,166, with a margin of error of 39. That is geographic eligibility information, not evidence of legal demand, search volume, competition, leads or revenue. For an ROI conversation, the distinction matters: a St. Marys target should not automatically be treated as a Camden County target, and neither should be silently expanded to another city, county or metropolitan area.
Recommended approach
Ask to see location definitions before reviewing performance. Decide whether the dashboard should distinguish St. Marys from Camden County and whether any wider geography belongs in the same view. Record the exact service-and-city targets, rather than treating a population figure as a marketing forecast.
