The Militarized Interstate Dispute (MID) dataset project has concluded at Penn State. Updated MID data through 2014 have been sent to the Correlates of War Project for posting.
The next iteration of the MID project will involve a consortium of scholars at different institutions, led by Faten Ghosn and Alex Braithwaite.
Questions about the existing data, especially for the years 2002-2014, can be addressed to Roseanne McManus. Please also see the FAQs tab.
