International travel can be very different depending on where you live. In a region like Europe, where much of the population lives within a few hours’ drive of the nearest international border, international travel accounts for up to two-thirds of the region’s tourism. In the United States, however, this statistic is reversed. Only about 20% of tourism revenue in North America comes from international tourism, with a considerable portion coming from neighbors north and south of the border. So unlike Europe, the United States’ largest tourism market is, in fact, homegrown and less susceptible to global events than international travel.
