On September 12, 2012 estimates for 1998 through 2010 were replaced with revised 2000 through 2010 data files from the Census Bureau. 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, including the assignment of a family health plan to all individuals in the household and the addition of a new variable to the allocation matrix (for more on the revisions see: http://www.census.gov/hhes/www/hlthins/data/revhlth/usernote.html). In September 2011, the Census Bureau released a new historical data series that incorporates the enhancements to the editing process. A working paper (found at: http://www.census.gov/hhes/www/hlthins/data/revhlth/SHADAC.pdf) released at the same time describes the revisions made and applies it to all years available: data files from the 2000 to 2010 ASECs.
Note: Maps use the natural break classification method, which reflects patterns
in the data by dividing the map into naturally occurring groups. Using statistical tools, this method
determines cut-off points for each group by identifying large gaps in data values.
Note: The District of Columbia, Puerto Rico and the U.S. Virgin Islands are
not included in maps and rankings because they are not states and therefore comparisons on many
indicators of child well being are not meaningful.
