Catoosa County, Cities and towns
Cities and towns in Catoosa County
The Census Bureau estimates 69,628 residents in Catoosa County for July 1, 2025, 1,594 more than in 2020 (+2.3%). That works out to 429 people per square mile of land. Fort Oglethorpe, the largest place on its list (10,868 residents in all), extends beyond Catoosa County, so no share of the total is worked out for it. Reported testing is thin here: 59 tests over 2008 to 2017, or 0.8 for every 1,000 residents (2025 estimate), where Georgia as a whole comes to 2.7.
From Fort Oglethorpe to Ringgold, CDC publishes no figure by town: each reads Catoosa County's.
