Footnotes:
Data presented for 2000 through 2008 are Vintage 2008 population estimates. Each year the U.S. Census Bureau revises their post-2000 estimates. Therefore, data presented here may differ from previously published estimates. Figures for 1990 and 2000 represent revised population estimates for July 1, 1990 and July 1, 2000, not actual Census counts from April 1, 1990 and April 1, 2000.
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.
