International travel can be vastly 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 makes up as much as two thirds of the region’s tourism. In the U.S., however, this statistic is flipped. Only around 20% of tourism revenue in North America is from international tourism, with a sizable share being from neighbors north and south of the border. So unlike Europe, America’s greatest tourism market is in fact homegrown and is less susceptible to global events than international travel.
