Hitting a three-decade record, 9% of U.S. children (7 million) were without health insurance in 2011. This represents one million more children with insurance than in 2000. In the last decade, 33 states and the District of Columbia saw a positive decline in uninsured children, while eight states saw no change and nine experienced an increase. Although many more children are insured than in the past, the rate of uninsured children varies across the country, from a low of 3% in Hawaii and Massachusetts to a high of 19% in Nevada.
