The number of uninsured Pennsylvanians is not growing.  According to data released by the U.S. Census Bureau, about one out of every eight Pennsylvanians under the age of 65 was uninsured in 2010-2011, roughly the same number as in 2008-2009.  16.2 percent under the age of 65 were covered by Medicaid in 2010-2011, the same as 2008-2009 but up sharply over previous years.
