Rural student enrollment grew by 9.1% nationally over a three year period, according to the methodology of the National Center for Education Statistics. Note that this mapping of "rural" districts is different from the metro/nonmetro county definition used frequently in the Daily Yonder. NCES's "rural" definition uses Census definitions of rural, factoring in the location of individual U.S. schools and their enrollments. Under this methodology, some nonmetro counties have no rural school districts. (Interactive map.)
