- A country is a distinct part of the world, such as a state, nation, or other political entity. When referring to a specific polity, the term “country” may refer to a sovereign state, states with limited recognition, constituent country, or a dependent territory. Most sovereign states, but not all countries, are members of the United Nations. There is no universal agreement on the number of “countries” in the world since several states have disputed sovereignty status, limited recognition and a number of non-sovereign entities are commonly called countries.

- Island country (Wikipedia)
An island country, island state, or island nation is a country whose primary territory consists of one or more islands or parts of islands. Approximately 25% of all independent countries are island countries. Island countries are historically more stable than many continental states but are vulnerable to conquest by naval superpowers. Indonesia is the largest and most populated island country in the world.
