Many families now need child care during nontraditional hours (NTH). Understanding the types of child care those families use for their young children has become a growing concern for policymakers interested in supporting the types of child care that meets families’ needs. We define nontraditional hours as 6:00 p.m. to 7:00 a.m. on weekdays and any hours on the weekend. To answer policy-relevant questions about nontraditional-hour child care, we analyzed data from the 2019 public use National Survey of Early Care and Education (NSECE). (author abstract)
