How many here a premium tax credit would reach

Cobb County has 40,867 uninsured residents earning inside the premium tax credit range, 48% of its uninsured total. That is near the 51% national median. Within that income band itself, 18.4% are uninsured — roughly one in 5 of the people the credit was designed for.

How many people here have no coverage

12.9% of Cobb County's 662,601 under-65 residents have no health coverage — 85,709 people. That is close to the Georgia rate of 14.0%, and puts Cobb County in the upper half of the 3,143 counties measured nationally (798th).

The people below the subsidy floor

23,010 of Cobb County's uninsured — 27%, close to the 31% typical nationally — earn under $22,025 a year. In Georgia that income is the coverage gap, and no marketplace plan reaches it.

Older residents here are better covered

15,012 people aged 50 to 64 in Cobb County have no coverage, a rate of 10.2% — lower than the 12.9% across all under-65 residents here, which is the usual pattern — people in their fifties and early sixties tend to be more settled in employer coverage. Age-rated premiums make this the most expensive group to cover before Medicare.
