The Cosmopolitan Leaders Dataset
How does pre-office experience living abroad affect a leader’s foreign policy behavior in office? Does cosmopolitan experience make a leader more peaceful?
We collect data on the pre-office foreign experience of leaders between 1875-2015 using the Archigos 4.1 leader list (Goemans, Gleditsch, and Chiozza 2009). While the data gathering is ongoing, we have collected data from over 113 states and 1,512 leaders in every region of the world.
