The physical, social, and economic health and well-being of adults and society are strongly influenced by 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 also includes new and emerging indicators of risk, reach, and resilience. Finally, this 2018 report reviews and notes changes since the 2015 Minnesota Early Childhood Risk and Reach report in the indicators of early childhood well-being and the availability and accessibility of key services from a county-level perspective. It is intended to be a resource for all early childhood stakeholders in order to guide and inform resource allocation and policy. [For the summary, see ED612388. For the 2015 report, see ED612381.]
