Each annual network Xijt = the number of times country i and country j were mentioned in a news story about terror or terrorism in year t. The networks are symmetric and contain valued data.

These tables are 250 x 250 matrices in which rows and columns identify states in the international system, and entry (i, j) contains the number of times countries i and j appeared in the same news story about terrorism. There is one table per day, for the date range 2000-01-01 through 2011-12-31. Updates will be available soon.
