Driven by insights into travel patterns, the Global Destinations Cities Index [PDF] provides a ranking of the 132 most visited cities around the world. More than just a travel tracker, the Index delivers deeper understanding of how people move around the world and speaks to the importance and prominence of the world’s cities as homes, destinations and engines of growth.
According to the study, London is projected to receive 18.82 million international visitors in 2015, just slightly ahead of second-ranked Bangkok. The two cities have topped the Index throughout its five-year history...
...In 2015, it is expected that nearly 383 million overnight trips will be made by international visitors between the Index’s 132 cities, representing a massive demand for goods, services and experiences as they spend at total of US$360 billion during their visits.
According to the UN report on World Urbanization Prospects, two-thirds of the world’s population will live in cities by 2050. By forecasting the number of international overnight travelers, the Global Destination Cities Index shows the infrastructure needed to meet the expectations of both locals and visitors.
