More than 114,000 students in New York City schools were homeless at some point during the last school year, according to the new data released by Advocates for Children of New York.

Nearly 3 percent more students lived in shelters or doubled up with friends or relatives compared to the previous year. It’s a smaller increase than in the past few years, but Randi Levine, the policy director at Advocates for Children of New York, said the numbers are still a cause for concern.

“We think that the city needs to invest more resources and attention in working with these students,” she said.

A spokeswoman for the city Department of Education said the de Blasio administration has introduced new initiatives to help homeless students, such as adding social workers toschools, placing families in shelters closer to their youngest child’s school, and providing yellow bus service to all students in grades K-6 living in city shelters.
