Definitions: Child population by age group.
Data presented for 2010 through 2011 are Vintage 2011 population estimates. Each year the U.S. Census Bureau revises their post-2010 estimates. Therefore, data presented here may differ from previously published estimates. Figures for 1990, 2000, and 2010 represent revised population estimates for July 1, 1990, July 1, 2000, and July1, 2010 - not actual Census counts from April 1, 1990, April 1, 2000, and April 1, 2010.

N.A. - Data not available.
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.
