Most research has focused on the benefits of integration in elementary and secondary schools, even though schools have become more segregated. But segregation in early childhood programs is even more pronounced than in K-12 classrooms, and that separation can lead to missed opportunities for contact and kinship during a critical point in child development. Our analysis is the first that aims to characterize segregation across early childhood education in the US. To ensure the possibility of integration, we analyze only ECE programs that serve at least five children. (author abstract)
