The National Survey of Early Care and Education (NSECE) documents the nation's current utilization and availability of early care and education (including school-age care), in order to deepen the understanding of the extent to which families' needs and preferences coordinate well with provider's offerings and constraints. The experiences of low-income families are of special interest as they are the focus of a significant component of early care and education/school-age (ECE/SA) public policy. The NSECE collected data from a nationally-representative sample including interviews in all fifty states and Washington, DC.
