The number of American children without insurance has dropped about 14 percent in the past three years, according to a new Georgetown University report.
Researchers found that the number of uninsured children dropped from 6.9 million in 2008 to 5.9 million in 2010 -- even with more children living in poverty because of the economy.
The progress is partly due to many states expanding eligibility for and access to the children's Medicaid program.
Experts added that the Affordable Care Act has played a key role in the improvement.
Florida made the most progress in insuring children. The state's number of uninsured children decreased by more than 160,000.
Both Minnesota and Kansas saw an increase.
Experts warned that the gains are fragile and can easily be reversed.
