The agency examined that there were over 846 million international tourist arrivals in 2006. The industry has become essential for many countries. Tourism generates different kinds of revenue that can contribute to the host country's welfare. Further, with the development of resorts, jobs are created in sectors directly or indirectly related to tourism such as transportation, accommodation and entertainment services.
