If you are interested in better understanding who does and does not purchase health insurance in the United States, check on the Census Bureau's revised figures on health insurance coverage.
In September 2011, the Census Bureau released revised figures on health insurance coverage from the 2000 to 2010 Current Population Survey Annual Social and Economic Supplements (CPS ASEC), reflecting enhancements to the editing process. Because the data after the enhancements is not consistent with earlier data, the Census Bureau introduced a new historical series (HIB-1 to HIB-8) and discontinued the HIA- series.
Here Are the Tables of Data:
For more information from the HIA historical series available from 1999 to 2009, go to the HIA Historical Series.
