This report assesses the changes in coverage patterns and health care costs that will occur nationally if major reforms are not enacted. The authors find that by 2015, there could be 59.7 million people uninsured. The number could swell to 67.6 million by 2020, up from an estimated 49.4 million in 2010. As premiums nearly double, employees in small firms would see offers of health insurance almost cut in half, dropping from 41 percent of firms offering insurance in 2010 to 23 percent in 2020. Individual spending could jump 34 percent by 2015 and 79 percent by 2020.
