The coral islands of Bermuda are composed of a layer 200 feet (60 metres) thick of marine limestone that caps an extinct and submerged volcanic mountain range rising more than 14,000 feet (4,300 metres) above the ocean floor.
English is the official language, but some Portuguese is also spoken. Christianity predominates, and about one-sixth of the population is Anglican.
Virtually all of Bermuda’s larger islands are inhabited, and Main Island has the largest concentration of people. Bermuda has one of the world’s highest population densities.
Bermuda has a predominantly market economy based on tourism and international finance.
In 1511 an island named “Bermudas” was depicted on a map in Spain. The Spanish navigator Fernández de Oviedo sailed close to the islands in 1515 and attributed their discovery to his countryman Juan Bermúdez, possibly as early as 1503.
