Definitions: The estimated percentage of an entering freshman class not graduating in 4 years.
The measure is derived from the Averaged Freshman Graduation Rate (AFGR), which uses aggregate student enrollment data to estimate the size of an incoming freshman class and aggregate counts of the number of regular diplomas awarded four years later.
Data Source: Population Reference Bureau, analysis of data from the U.S. Department of Education.

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.
