The Centers for Disease Control and Prevention actually reported that 54.5 million people were uninsured for at least part of the year. Health Insurance Coverage: Early Release of Estimates from the National Health Interview Survey, 2006. Centers for Disease Control.
http://www.cdc.gov/nchs/data/nhis/early ... 200706.pdf The amount of uninsured is rising every year, as premiums continue to skyrocket and wages stagnate. From 2004 to 2005 the number of uninsured rose 1.3 million, and rose up nearly 6 million from 2001-2005.

With 44.8 uninsured in 2005, in 2007 the number will be much higher. Professors Todd Gilmer and Richard Kronick, in "It's The Premiums, Stupid: Projections Of The Uninsured Through 2013," Health Affairs, 10.1377/hlthaff.w5.143, "project that the number of non-elderly uninsured Americans will grow from forty-five million in 2003 to fifty-six million by 2013." According to these authors, by now the number of non-elderly uninsured by this date clearly would be nearly 50 million.
