S – NAEP reporting standards not met. 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.
