The name España is of uncertain origin; from it derived the Hispania of the roman Empire.Important regions within the modern nation are the Basque Country (País Vasco), the Catalan-Valencian-Balearic area, and Galicia—each of which has its own language and a strong regional identity.But other measures of difference, in addition to a separate language, distinguish Cataluña from the rest of Spain.Among these is Cataluña's deeply commercial and mercantile bent, which has underlain Catalan economic development and power in both past and present.
The country's interior, while transected by various mountain ranges, is high plateau, or meseta, generally divided into the northern and southern mesetas.Other entities in Iberia are the Principality of Andorra in the Pyrenees and Gibraltar, which is under British sovereignty and is located on the south coast. The Atlantic Ocean washes Spain's north coast, the far northwest corner adjacent to Portugal, and the far southwestern zone between the Portuguese border and the Strait of Gibraltar.Spain is separated from North Africa on the south by the Strait of Gibraltar and the Mediterranean Sea, which also washes Spain's entire east coast.The Puerta del Sol is at kilometer zero for Spain's road system. Spain's population of 39,852,651 in early 1999 represented a slight decline from levels earlier in the decade.The population had increased significantly in every previous decade of the twentieth century, rising from under nineteen million in 1900.
