Mayor Marty Walsh pushed back against a Boston Globe report that a pattern of segregation is emerging in Boston Public Schools.

The Globe data show that nearly 60 percent of the city’s schools meet the definition of being intensely segregated, meaning students of color take up at least 90 percent of the seats. Walsh told WGBH News he refuses to believe that the report is true.

“I think the indication that BPS is resegregating, the report was wrong and misleading,” Walsh said during an interview with Boston Public Radio Friday, appearing alongside Boston Police Commissioner William Gross. “Boston public schools are very highly diverse schools, and we need to celebrate that. We need to make sure that we continue to raise the level of education in all of our schools across every school.”

According to the Globe, only 42 percent of schools were considered segregated two decades ago. The report says the nearly 20 percent increase is a consequence of more students attending schools in their own neighborhoods, similar to the way they did before court-ordered busing.

Many of the schools are low-performing, and the report notes an increase in schools where the majority of the population is white, from two to five.

“That report stated that five schools were so-called “majority white,” ... five schools out of 125 schools in the city of Boston,” Walsh said. “So I don’t think that we’re going back to segregation, but I do think, I don’t think this, I know this, that we have a lot of work to do to bring our schools to the standard of ... some of the other great schools in our city.”

Correction: An earlier version of this story quoted included a quote from Mayor Marty Walsh that gave an incorrect definition of the term "majority white" as it applies to Boston Public Schools. According to BPS officials, majority white schools are between 51 and 60 percent white. The post has been updated to remove the reference.
