It’s not a quarter of all people, just adults and Canada and Mexico are both pretty easy for a lot of Americans. Plus cruises and/or resort trips to the Caribbean and there’s plenty of people who have “been to another country” without ever having really experienced another country.
A quarter going to 5 or more countries feels incredibly generous.
Hell a quarter never traveling also feels like a huge under estimate.
Granted, unlike, Europe, we aren’t all a 30 minute drive from another country.
