Students attend a class at Chalmers Elementary school in Chicago, Wednesday, July 13, 2022. America's big cities are seeing their schools shrink, with more and more of their schools serving small numbers of students. Those small schools are expensive to run and often still can't offer everything students need (now more than ever), like nurses and music programs. Chicago and New York City are among the places that have spent COVID relief money to keep schools open, prioritizing stability for students and families. But that has come with tradeoffs. And as federal funds dry up and enrollment falls, it may not be enough to prevent districts from closing schools. (AP Photo/Nam Y. Huh)
