Islanddominated

Islanddominated is an adjective used to describe a situation in which island regions or island nations wield disproportionate influence within a larger system. It signals that geographic insularity, resource endowment, or strategic location concentrates power, trade, or cultural primacy on one or more islands relative to their land area or population.

As a neologism, it lacks a formal, universal definition. In geography, political science, and economics, islanddomination is used descriptively to discuss asymmetries that arise from archipelagic conditions, such as concentrated governance, infrastructure, or economic activity on specific islands.

In economic networks, islanddominated systems may show that a handful of coastal or highly connected islands account for most trade flows or investment, while hinterland regions remain relatively peripheral. In governance terms, capital cities located on a few hubs can exert outsized influence on national policy, with other islands playing subordinate roles.

Measuring islanddomination is contested; researchers may compare shares of GDP, port throughput, investment, or political weight by island. Critics argue that the label risks oversimplifying complex regional dynamics and that it can obscure intra-island heterogeneity.
