We analysed the 100 most visited cities from 2018 and 2008 (according to Euromonitor) and 50 most visited countries from 2017 and 2007 (according to the World Tourism Organization).
Note: Some cities and countries had to be excluded due to lack of Google Trends data.
We also chose to exclude Mecca as while this does rank among the most visited cities in the world, this is largely due to the Hajj pilgrimage, rather than people visiting for holidays.
We then used Google Trends to analyse the search term ‘[Country Name] Holidays’ for each (for example ‘London Holidays’ or ‘USA Holidays’).
For each country, we counted the total worldwide search interest for each of the last ten years, before calculating the % difference from 2009 to 2018.
Note: While Kolkata came out as the city with the biggest popularity increase, we chose to exclude this on the basis that searches for that term will have seen a significant increase due to the city changing its name from Calcutta fairly recently.
