The minimum-distance database records the minimum distances for all polities in the Gleditsch-Ward country list, within 950 km of each other. 

This is calculated as the shortest distance in statute kilometers between points on the outer boundaries for two polities, regardless of whether the states are separated by land or sea, given the borders in place in a particular time period.
