Aruba is one of the four constituent countries that form the Kingdom of the Netherlands, together with the Netherlands, Curaçao, and Sint Maarten whose citizens share a single nationality: Dutch citizen.
Aruba has no administrative subdivisions, but for census purposes is divided into 8 regions. Its capital is Oranjestad. Unlike much of the Caribbean region, Aruba has a dry climate and an arid, cactus-strewn landscape.
This climate has helped tourism as visitors to the island can reliably expect warm, sunny weather. It has a land area of 179 square kilometres (69 sq mi) and is densely populated with a total of 101,484 inhabitants at the 2010 Census. It lies outside the hurricane belt. It is also home to the endemic Aruba Island Rattlesnake.
