When referring to international tourism, a distinction can be made between outbound tourists (those leaving their country of origin) and inbound tourists (those arriving in country different from their usual country of destination). Any international tourist is both inbound and outbound at the same time, with the distinction being made from the perspective of the country of origin or the country of destination. Accordingly, the cumulative number of inbound trips will always exceed total number of outbound trips at a global scale, since one outbound trip must translate into at least, but possibly more than, one inbound trip
