Abstract

Dataset capturing the distances (in km) between the capitals of all states in the international system--including most (overlooked) microstates. This is a directed dyad dataset (with country codes from the Correlates of War Project), which easily facilitates merging with other directed dyad datasets--or non-directed dyad datasets without a standardized ordering of countries within dyads.
