This map shows U.S. Peace Index: Changes in Peacefulness 1991 - 2009.
First-ever ranking of peace in the U.S. shows the nation has become more peaceful since 1995.
The United States Peace Index (USPI) is the first in a series of national peace indices that will build on the work of the Institute for Economics and Peace (IEP) in measuring and understanding the fabric of peace. The Institute produces the Global Peace Index which is the first ever study to methodically rank the nations of the world by their peacefulness and to identify potential drivers of peace. The GPI has become a valued resource and is used by academics, think tanks and governments around the world.
