Relative High School Completion Rates in Appalachia, 1980

(County Rates as a Percentage of the U.S. Average)

A high school completion rate is the percentage of adults, 25 years and over, completing 12 years or more of school. The percent of the U.S. average is computed by dividing the county high school completion rate by the national average and multiplying by 100. The map uses critical breaks such as the national average to organize the data into groups of common values.
