2. United States

The only non-Nordic country on our top five, the United States is one of the most diverse countries on Earth, geographically and ethnically. The wide variety of tourist attractions partly leads Americans to keep their trips domestic. Though the average American takes 6.7 trips each year, only 0.2 of those (less than 3%) are abroad. With many families spread out across multiple cities, many domestic trips are to reunite for the holidays. Despite their frequent travels, Americans are among the least well-traveled internationally among citizens from Western countries.
