I construct spatial measures of conflict for all states in the international system from 1946–2008. For each state, the spatial measures count the number of connected states engaged in a rivalry and/or engaged in a militarized dispute, normalized by the number of neighbors. These data enable analyses of how conflict and rivalry in a state’s neighborhood influence a variety of important political phenomena at the domestic or interstate level.

I also include in this dataset spatial measures of the density of IO membership in a state’s neighborhood, average level of democracy, and level of economic integration.
