The Passport Index

The Passport Index is an interactive online tool that provides its users with insights about passports, including the ability to compare and rank the world's passports. Rankings are based on the freedom of movement and visa-free travel open to holders of particular passports. The site allows the display of various territories' passports using a variety of filters such as region and passport cover colour.
"World Openness Score".
The "World Openness Score" is a measure that tracks the ability of the world's population to travel visa-free. It has grown from 17,904 to 20,143 between 2015 and August 2018.
Methodology.
The Passport Index compares passports mainly on their visa-free travel options, but also on how welcoming the countries are to visiting foreigners. In its ranking, The Passport Index looks at 193 United Nations member countries and six territories, which include ROC Taiwan, Macao (SAR China), Hong Kong (SAR China), Kosovo, Palestinian Territory and the Vatican. Territories annexed to other countries such as Norfolk Island (Australia), French Polynesia (France), British Virgin Islands (Britain) are excluded.
Results.
Passport Index rankings are in real-time and continue to vary as new changes to visa agreements are made. For the most part, the Top 10 places have been occupied by European countries with the exception of Singapore.
Between 2017 and 2018, at top of the list with a visa-free score of 165 were Singapore and Germany, while the United States of America, South Korea, France, Denmark and Sweden were among the 11 countries that shared the second spot with a score of 164. The UAE passport now takes fourth place with a visa-free score of 179.
Case studies.
United Arab Emirates.
In 2017, The Passport Index was assigned to monitor the development of the newly launched UAE Passport Force Initiative, with the aim to position the Emirati passport on the list of the five most powerful passports in the world by 2021. By 31 October 2018, the Emirati passport had already reached fourth place. However in 2021, the passport's power trend dropped secondary to the COVID pandemic.
Background.
The Passport Index was launched by "Arton Capital", a financial services firm with a head office in Montreal, in 2014.
