Christmas Island

With an area of just 135 square kilometers, Christmas Island is geographically tiny, smaller than many major global cities. However, its strategic location in the Indian Ocean and its classification under the 'Australia and New Zealand' subregion gives it disproportionate geopolitical and environmental importance, particularly regarding migration and biodiversity.

The capital, Flying Fish Cove, is the only significant settlement on the island. Given the island's small size and high proportion of national park, it is highly probable that the vast majority, if not all, of the 1,692 residents live within or immediately adjacent to this single capital area, creating a highly centralized community structure.

Despite its small population, Christmas Island has a relatively high density of approximately 12.5 people per square kilometer (1692 people / 135 km²). While not high by urban standards, this density is significant for a remote island territory largely consisting of protected national parkland, suggesting concentrated settlement areas.

Christmas Island is geographically located in Oceania, but it is explicitly categorized within the 'Australia and New Zealand' subregion. This highlights its political status as an external territory of Australia, linking its governance and economic structure strongly to the larger continent rather than typical Pacific Island nations.
