This will be the sixth edition of the UNWTO International Conference on Tourism Statistics. Over the course of the previous five conferences in Ottawa (1990), Nice (1999), Vancouver (2001), Iguazu (2005) and Bali (2009), the core components of tourism statistics have been defined and established. These have been landmark events having decisively contributed to the establishment of key concepts, definitions, classifications and indicators which are nowadays viewed as the foundation of the System of Tourism Statistics.
