Role

gateway

Denmark acts as a gateway because its network-relative degree, reach, or gateway-share signal is elevated; the gateway-share signal is around the 69th percentile.

Role labels are network-relative classifications derived from degree, reachable-country count, bridge coverage, and gateway concentration within the country-topology graph.
