The physical, social, and economic health and wellbeing of adults and society are strongly influenced by both positive and negative experiences in early childhood. The most cost-efficient time to build foundational skills, to assure the healthy development of all young children, to break the cycle of disadvantage for vulnerable children, and to prevent achievement and health inequities is in the very early stages of development. This report describes potential risks to the healthy development of young children and the extent of coverage of publicly-funded services to meet their early learning, health, and basic needs. It is intended to be a resource for all early childhood stakeholders in order to guide and inform resource allocation and policy. One benefit of compiling data in such a format is that these indicators can be periodically assessed for continuity, change, and integration over time. [For the summary, see ED612383.]
