Although called Ibiza in English and Spanish, the official name is the Catalan Eivissa (as restored in 1986) and its inhabitants call it the Vila d'Eivissa or simply Vila ("Town"). It is divided into two main parts: the old town, called the Dalt Vila (literally "Upper Town"), located on a little mountain by the sea, and the modern part, called the Eixample ("extension").
The city, which has a population of 49,768 (2012), is the capital and most populous settlement of the island and of the Pine Islands group, which includes Ibiza and Formentera.
