Ever wandered through Paris and got the feeling that every other person is a tourist? You wouldn’t be far wrong.

Of the 20 most visited cities on Earth, the French capital is where overseas visitors outnumber locals the most, according to research by On The Go Tours.

Just 2.2 million people call Paris home, but around 18 million travelled there in 2016. So for every Parisian the city attracts more than eight tourists each year - a 704 per cent increase.

Of the top 20 cities for visitors, none sees its resident population dwarfed in such a significant manner. London, for example, attracts 19.9 million tourists annually. But it is home to 8.7 million, so that’s an increase of just 129 per cent.

The closest rival, according to the study, is Kuala Lumpur, which has 1.7 million residents but 12 million annual visitors - and increase of 595 per cent. Dubai, Milan and Barcelona complete the top five.

Absent from the list, however, is Venice. On The Go Tours examined the 20 most visited cities according to Mastercard’s Global Destinations Cities Index, which only takes into account overnight stays. Most of Venice’s annual visitors (around 25 million according to the local tourist board) are day-trippers or cruise ship passengers, so it doesn’t appear. With a resident population of just 55,000, that figure of 25 million tourists represents an increase of 45,554 per cent. So surely Venice is the most touristy city on the planet?

Another contender, though some way behind Venice, is Dubrovnik. It is not among the world’s 20 most visited cities, but attracts around two million tourists a year, around half of which are cruise passengers. And with a resident population of around 40,000, that’s a 5,100 per cent increase.

Florence also does not appear on Mastercard’s list, but is estimated to draw more than 16 million tourists each year. That’s a 4,310 per cent increase on its population of 380,000.

Iceland, meanwhile, has soared in popularity in recent years. Around 1.5 million visited the country last year (up from just 459,000 in 2010 and 200,000 in 1996), around 95 per cent of whom stayed in the capital. Reykjavik’s population is just 120,000, give or take, so that’s an increase of around 1,343 per cent. So while Paris is certainly touristy, it’s got some stiff competition.

What’s the most touristy country in the world?

The world's most popular country? According to figures for 2015, it's France, with 84.5 million overseas visitors. Second is the US, on 77.5m, third is Spain on 68.2m, while the UK comes eighth at 34.4m.

But what happens if we take visitor numbers and divide them by a destination's population, to give the number of tourists per resident? As you'll see from the map below, which uses tourism arrivals from 2014, you get a very different set of results.

The tiny principality of Andorra tops the charts (you'll need to zoom in to see it). It welcomed 2.36m tourists in 2014, but just 70,000 people call it home. That works out at 33.5 tourists per resident.

Macau, the gambling hub, comes second - with 24.8 tourists per resident - followed by a pair of Caribbean gems - the British Virgin Islands (12.8) and the Turks and Caicos Islands (10.4). In total, there are 51 destinations where tourists outnumber locals - and we've gone to the trouble of listing them all below.

One country is glaringly absent, however. The Vatican City does not appear on The World Bank's database for 2014, so doesn't appear on our maps, but it attracts around five million people each year and has a resident population of just 842. That's almost 6,000 tourists per citizen - putting it way out in front.
