This book provides a basic understanding and concise overview of the nature of population health, the factors that make a new paradigm necessary, and the attributes associated with this unique approach to community health improvement. Written in a very accessible way, the book describes the definition of population health, the attributes of population health, and what population health is and is not. It emphasizes the extent to which the population health model revolutionizes the approach to community health improvement within a contemporary context, beginning with a redefining of such common concepts as "health", "healthcare", "health status", and "health needs assessment". As such, this book is a valuable read for practitioners and professionals who need to be familiar with the population health approach but are not likely to try to implement it.
