 ıPercentage of population is calculated by dividing the child count by the population estimate for children in
the age or race/ethnicity category and multiplying the result by 100 to get a percentage.
 
The population estimates used for 1999 are intercensal estimates based on the 1990 and 2000 Censuses. For
2000 through 2003, population data are July 1 estimates, released October 2004.  These data are based on
the 2000 decennial census.  The population estimates are from the Population Estimates Program, U.S.
