About IEP

The Institute for Economics and Peace (IEP) is a non-profit research organization dedicated to shifting the world’s focus to peace as a positive, achievable, and tangible measure of human well-being and progress.

It achieves its goals by developing new conceptual frameworks to define peacefulness; providing metrics for measurement; uncovering the relationship between peace, business and prosperity, and by promoting a better understanding of the cultural, economic and political factors that drive peacefulness.

National Peace Indices

IEP has launched the first in a series of nation-specific peace indices which allow regional differences within countries to be measured and taken into account.

The U.S. Peace Index (USPI) ranks the fifty U.S. states based on their levels of peace; it shows Maine is the most peaceful U.S. state, while Louisiana is ranked the least peaceful.
