The microstate is an independent state with a very small area and population. These states have relatively large influence in the United Nations due to the principle of one country, one vote. The smallest microstate is the Vatican, with 911 citizens and 44 hectares, according to the 2003 census. The Knights of Malta, headquartered in Rome, the capital of Italy, are practically an independent state with no surface area. The Vatican and the Knights of Malta are both non-members of the UN and only have permanent observer status. Microstates should not be confused with microstates that are not considered independent states. Private regions that have not achieved full independence, such as the Channel Islands, are also not microstates.
