Island country

state whose primary territory consists of one or more islands or parts of islands

An island country (also sometimes called island nation or borderless country) is a country that is made up only of islands. They are not connected by land to any other nation. Each island only belongs to that country, so there are no borders. Examples of borderless countries are Iceland, Japan and Madagascar.

Many island nations get money from fishing.
