(AP) — Wichita school officials say they are serving a record number of homeless students this year.

As of Monday, educators and social workers said they had identified 2,251 homeless children attending the city’s public schools. That’s 518 more than last year.

District officials say just under 50,000 students attend Wichita schools, meaning more than 4 percent of the city’s schoolchildren are homeless,

Cynthia Martinez, who is in charge of finding homeless children in the Wichita district, says most of the homeless children are from working families, rather than from families on welfare. Many of them are living with other families but the district identifies them as homeless.
