IEP Indices & Data

IEP believes a thorough fact-based approach to measurement is the first step to achieving the goal of more peaceful societies.

While a peaceful society is a goal most people would aspire to, surprisingly little research has been focused on measuring the texture of peace beyond the simple conception of whether nation states are at war or not. While research energy has been devoted to understanding the causes of war very little time has been devoted to understanding the social, political and economic determinants of peace.

Global Peace Index

IEP’s Global Peace Index (GPI) was created to measure not just the relative states of peace in the nations of the world, but to also create a framework which allows us to track and compare how peace develops over time.

See the Global Peace Index page for findings, scores, reports, links and more.

National Peace Indices

IEP is also creating a series of nation-specific peace indices which allow regional differences within countries to be measured and taken in to account.

The fist of such indices is the United States Peace Index (USPI), launched in April 2011. The first-ever ranking of peace in the U.S., the USPI shows the nation has become more peaceful since 1995.
