It has been over six decades since the Supreme Court ruled states establishing separate public schools for black and white students unconstitutional. Yet school segregation persists today, because most students are assigned schools based on their address, and many neighborhoods are still racially homogeneous.

More than four in five traditional public schools in the country have a student population in which a majority of students are the same race, according to the National Center for Education Statistics. Sixty percent of traditional public schools are majority white, while 15 percent are majority Hispanic and 9 percent are majority black.
