The Spanish city of 1.6 million people welcomes about 30 million visitors per year. Residents in popular downtown areas are now outnumbered by visitors, and a new local survey shows tourism has become the biggest concern among locals, surpassing unemployment. So Barcelona's city council was forced to act, introducing new rules on Friday to clamp down tourism in the city center. That's nice, but we're conscious that people who live in Barcelona are having more and more problems with tourism," a city council spokesperson told CNNMoney. Barcelona's hotel association said it did not support the city council rules and said it hurt "one of the main economic engines of the city."
