Dario Caldara and Matteo Iacoviello construct a monthly index of Geopolitical Risk (GPR Index) counting the occurrence of words related to geopolitical tensions in leading international newspapers. The GPR index spikes around the Gulf War, after 9/11, during the 2003 Iraq invasion, during the 2014 Russia-Ukraine crisis, and after the Paris terrorist attacks.

The Benchmark Index (GPR) uses 11 newspapers and starts in 1985.
The Historical Index (GPRH) uses 3 newspapers and starts in 1899.
This is work in progress. We welcome kudos, comments and suggestions!

Our DATA updated through the end of August 2017 (and including preliminary September 2017 data using searches until September 10th) can be found here [ last update: Sep11,2017 ]
The data also include (beta-version) country-specific GPR indices for 18 emerging economies (Caldara, Iacoviello and Aaron Markiewitz, "Country-Specific Geopolitical Risk")
The main data are updated for each month around the 10th of the following month.

Detailed description of the GPR index
The Caldara and Iacoviello GPR index reflects automated text-search results of the electronic archives of 11 national and international newspapers: The Boston Globe, Chicago Tribune, The Daily Telegraph, Financial Times, The Globe and Mail, The Guardian, Los Angeles Times, The New York Times, The Times, The Wall Street Journal, and The Washington Post. Caldara and Iacoviello calculate the index by counting the number of articles related to geopolitical risk in each newspaper for each month (as a share of the total number of news articles). The index is then normalized to average a value of 100 in the 2000-2009 decade.
The search identifies articles containing references to six groups of words: Group 1 includes words associated with explicit mentions of geopolitical risk, as well as mentions of military-related tensions involving large regions of the world and a U.S. involvement. Group 2 includes words directly related to nuclear tensions. Groups 3 and 4 include mentions related to war threats and terrorist threats, respectively. Finally, Groups 5 and 6 aim at capturing press coverage of actual adverse geopolitical events (as opposed to just risks) which can be reasonably expected to lead to increases in geopolitical uncertainty, such as terrorist acts or the beginning of a war.
Based on the search groups above, Caldara and Iacoviello further disentangle the direct effect of adverse geopolitical events from the effect of pure geopolitical risks by constructing two indexes. The Geopolitical Threats (GPT) index only includes words belonging to Search groups 1 to 4 above. The Geopolitical Acts (GPA) index only includes words belonging to Search groups 5 and 6.
