Aruba is an island and a constituent country of the Kingdom of the Netherlands in the southern Caribbean Sea, located about 1,600 kilometres (990 mi) west of the main part of the Lesser Antilles and 29 kilometres (18 mi) north of the coast of Venezuela. It measures 32 kilometres (20 mi) long from its northwestern to its southeastern end and 10 kilometres (6 mi) across at its widest point. Together with Bonaire and Curaçao, Aruba forms a group referred to as the ABC islands. Collectively, Aruba and the other Dutch islands in the Caribbean are often called the Dutch Caribbean. Aruba is one of the four countries that form the Kingdom of the Netherlands, along with the Netherlands, Curaçao, and Sint Maarten; the citizens of these countries are all Dutch nationals. Aruba has no administrative subdivisions, but, for census purposes, is divided into eight regions. Its capital is Oranjestad. The florin (sign: Afl.; code: AWG) is the currency of Aruba. It is subdivided into 100 cents. The florin was introduced in 1986, replacing the Netherlands Antillean guilder at par. Although the Aruban florin is pegged to the United States dollar at the rate of 1.79 florin per USD, the commonly used street value is at 1.75 florin per USD.
