what is the percentage of schools that wear uniforms
School uniforms by country As of August 2013, almost one fifth of all American schools required their students to wear uniforms (Flam). This 20 percent of schools requiring uniforms is six percent higher than in 2003, the U.S. Department of Education reported.[citation needed] The uniform requirement is more common in lower socio-economic schools, where more than three-fourths of the school's student population receives free or reduced lunch ("Fast"). Forty-seven percent of low income schools require uniforms, whereas only about six percent of high socio-economic schools require uniforms ("Fast").[citation needed]
