The area around the city of Malaga, known as Costa del Sol, in Spain, evolved from an initial vocation of receiving minority tourism of Anglo-Saxon origin, which sought warm weather, to a clear specialization in mass tourism from Europe and based on the sun and beach segment, which occupied a large part of the active population.
