How many countries have you actually visited?

Only as a party trick. What the count measures is breadth, and breadth correlates with income and education rather than with curiosity or judgement. Someone who spent three months in one country knows it far better than someone who passed through 30 for a day each. Read your percentile as a fact about the population you live in, and leave it there.

Whatever rule you apply consistently. No official standard exists. Some counters include territories such as Gibraltar or Puerto Rico; others stick to the 193 UN member states, while the Travelers' Century Club list stretches to 330. Airport transits and day trips are where the arguments start. Pick your rule, keep to it, and your percentile stays comparable with everyone else's.

27%, on Pew Research 2021. Among households under $30,000 a year it rises to 48%, and with only about 48 valid passports for every 100 Americans in 2023, most people who haven't been abroad would need a passport before they could go. Geography does most of the explaining. There are two land borders, then an ocean, and six time zones across the states to fill a holiday with before you reach either.

Distance first. Most of Europe sits within a 3 to 4 hour flight of the UK, and France or Belgium fits inside a long weekend by train. Time off does the rest. UK statutory annual leave is 28 days, while the US has no federal mandate, and BLS figures for March 2025 put 31% of private-sector workers on 10 to 14 paid vacation days after a year, which rules out the slow multi-country trip Europeans take for granted.

193 United Nations member states plus 2 observer states, Vatican City and Palestine, so 195 by the usual standard. Prolific lifetime travellers tend to top out between 100 and 150. Clearing all 195 means money, years, active conflict zones, and places such as North Korea, Turkmenistan and Eritrea that take months of paperwork. A realistic stretch target is 50 to 80, which already clears the 95th percentile in both countries.

More common over the long run, with a hole punched through 2020 to 2021. UK residents made 94.6 million visits abroad in 2024, just past the 93.1 million of 2019, and global arrivals had come back to 88% of 2019 levels in 2023 on UN Tourism figures. Cheap seats did most of it. Budget airlines put a week in Europe inside household budgets that could never previously reach it.

Low. There were 160.7 million valid US passports in 2023, about 48 for every 100 Americans, while 86.5% of residents in England and Wales held at least one passport at the 2021 Census. Part of that is the size of the domestic option, since you can spend a whole life on American holidays and never need the document. In the EU, crossing a border barely registers as international travel at all, which quietly inflates the counts on the other side.

The gains are real and they do not scale with the count. Nawijn and colleagues found in 2010 that anticipating a holiday lifts wellbeing more than the period after it does, so a good deal of the benefit is in the planning. Wider work links international travel to greater openness to experience and lower in-group bias, at modest effect sizes. One trip you actually engage with beats ten stamps in a book.

Somewhere around 10 to 15, though that comes from assembling ONS and ABTA evidence rather than from a survey that asked the question directly. Generation T, ABTA's label for 18 to 24 year olds, averaged 2.7 holidays abroad in the 12 months to August 2023. Add a gap year and student Interrail trips on top and the count climbs quickly.
