Of the 129 schools that face the chopping block in the Chicago Public Schools (CPS) next wave of school closures, 117 have a majority African-American student body.

According to an analysis by the Chicago Sun-Times, that translates to the statistic that nine out of 10 students facing school closures are black.

“It bothers me that schools that are in mixed neighborhoods, schools that are mostly Hispanic or Caucasian, they don’t seem to show interest to close them,” Willetta Gary, a substitute teacher at Shoop Academy, told the newspaper. “Children fare best when they can attend school in their own neighborhood where they live.”

CPS chief executive officer Barbara Byrd-Bennett says race is not an issue during school closures, adding that instead she is making an attempt to “right size” the district.

CPS is using building utilization as criteria for the next wave of school closures, eliminating roughly 100,000 empty seats. According to the district, nearly 140 schools are more than half empty. The school system has classroom space for more than 500,000 students, but just over 400,000 students are enrolled.

“Every child in every neighborhood in Chicago deserves to have a high-quality education that will prepare them to succeed in life,” Byrd-Bennett said in an emailed statement to the Sun-Times. “These numbers show that right now, that is not happening, and a disproportionately high rate of our African-American children are in schools that lack the resources necessary to give them an education we can all be proud of.”
