Along with its cultural, leisure and recreational functions tourism contributes significantly (both directly and indirectly) to the world's economy and employment. It contributes to GDP even more than the automotive industry in all the regions throughout the globe: three times as much in Americas and two times as much in Europe, according to the World Travel & Tourism Council's 2017 research. In many countries tourism is the key source of jobs for their population. Thus, in Macau, one of the two Special Administrative Regions of the People's Republic of China, a half of population is employed in the travel and tourism sphere.
