The Index combines measures from multiple sources and perspectives to offer a broad view of the health protections in place for the nation as a whole and for each U.S. state. The Index identifies strengths as well as gaps in the protections needed to keep people safe and healthy in the face of large-scale public health threats, and it tracks how these protections vary across the United States and change over time.

Drawing data from 64 sources, the National Health Security Preparedness Index is the most comprehensive look at each state's preparedness to date. It is also the first national index that looks at the nation’s health security by collectively measuring the preparedness of the states. The display of results on the NHSPI website takes into account both preparedness and model complexities; however, states face varying threats, apply preparedness principles in locally relevant ways, and have unique interdependencies. Explore the interactive map below to understand the range of influences on America’s health security and preparedness.
