Henley Passport Index

Henley Passport Index is a mathematics topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Henley Passport Index rather than just read about it. In short: The Henley Passport Index is an annual global ranking of countries according to the travel freedom allowed by those countries' ordinary passports for their citizens. The index was created by Christian Kälin and launched in 2005 as Henley & Partners Visa Restrictions Index.

Key takeaways

  • Henley Passport Index belongs to mathematics; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Henley Passport Index to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Henley Passport Index from memory before moving on to harder problems.

Reference excerpt

The Henley Passport Index is an annual global ranking of countries according to the travel freedom allowed by those countries' ordinary passports for their citizens. The index was created by Christian Kälin and launched in 2005 as Henley & Partners Visa Restrictions Index. Its name was changed to Henley Passport Index in January 2018. The index is updated on a quarterly basis to reflect changes in global visa policies. The index annually ranks 199 passports of the world by the number of countries that their holders can travel to without requiring a visa. The number of countries that a specific passport can access becomes its visa-free "score". The data is obtained from the International Air Transport Association (IATA)'s Timatic documentation requirements database.

Definition of the index The Henley Passport index ranks passports according to the number of destinations that can be reached using a particular country's ordinary passport without the need of a prior visa ("visa-free"). The survey ranks 199 passports against 227 destination countries, territories, and micro-states. The IATA maintains a database of travel information worldwide and all destinations that are in the IATA database are considered by the index. However, because not all territories issue passports, there are far fewer passports ranked than destinations about which queries are made.

Method To determine the score for each country or territory, its passport is checked against the IATA Timatic database in several steps:

Each of the 199 passports on the list is checked against all 227 possible travel destinations for which travel restriction information exists in the IATA database. The score is updated throughout the year. Each query must satisfy certain conditions: passport is issued in the country of nationality passport holder is an adult citizen of the country that issued the passport and a lone traveller, not part of a tourist group entry is sought for tourism or business the stay is a minimum of three days Further conditions: queries are made only for holders of normal passports, not diplomatic, service, emergency, or temporary passports; and other travel documents are disregarded passport holders need not meet any complex requirements for entry (for example, possessing a government-issued letter, translations, or empty pages) passport holders have all necessary vaccinations and certificates passport holders are arriving at and departing from the same airport passport holders are seeking a short stay rather than a transit the port of entry is a major city or capital, in cases where this is required requirements by the destination country or territory regarding a particular length of validity of passports are disregarded passport holders meet all basic requirements for entry (for example, holding a hotel reservation or having proof of sufficient funds or return tickets) advance passenger information and advance approval to board are not considered to be a visa requirement or travel restriction, neither is the requirement to pay airport tax If no visa is required for passport holders from a particular country or territory to enter the destination, then that passport scores 1. The passport also scores 1 if a visa on arrival, a visitor's permit, or an automatically approved electronic travel authority (ETA) can be obtained because they do not require manual pre-departure government approval, perhaps because of specific visa-waiver programs in place. Where visas are needed, or where passport holders must get manually government-approved electronic visas (e-Visas) before departure, a score of 0 is given. If passport holders must get government approval before leaving in order to obtain a visa on arrival, this also scores 0. The score for each passport is then totalled by adding up its scores for all destinations. The index ignores temporary restrictions or airspace closures. It considers mobility data based on national GDPs and the percentage of global wealth that the country's passport could provide access to.

Rankings

2026 Henley Passport Index According to 2026 Henley Passport Index, Singapore retains the top spot as the world's most powerful passport, giving visa-free access to 192 out of the 227 destinations worldwide to its holders. Japan, South Korea and the United Arab Emirates are second in the ranking. The UAE passport has moved up the ranking by eight places making it the first in the Middle East. The third spot is taken by Sweden. The Afghan passport is ranked last in the index making it the least powerful passport, which gives its holders visa-free access to 23 countries. The South African passport is ranked in the top 50 after a decade, rising by 10% between 2024 and 2025. Seychelles and Mauritius retained their positions in the index as Africa’s highest ranked passports. Seychelles, which was ranked at 23rd offers visa-free access to 155 destinations and Mauritius ranked at 26 gives access to 148 destinations.

2024 Henley Passport Index As of 16 July 2024, the Singaporean passport offers holders visa-free or visa-on-arrival access to a total of 195 countries and territories, followed by the Japanese, French, German, Italian, and Spanish passports offer holders visa-free or visa-on-arrival access to a total of 193 countries followed by the Austrian, Finnish, Irish, Luxembourgish, Dutch, South Korean and Swedish passports, each offering 192 visa-free or visa-on-arrival countries and territories to its holders. These rankings were subsequently followed by the Belgian, Danish, New Zealand, Norwegian, Swiss, and British passports, each offering visa-free or visa-on-arrival travel to 191 countries and territories. While the 2024 Henley Passport Index shows a worldwide improvement in access to visa-free travel, the gap between the top and the bottom ranked countries has widened. Asian countries like Japan and Singapore have dominated the top position in the Index for the last five years. The Afghan passport has once again been labelled by the index as the least powerful passport in the world, with its nationals only able to visit 28 destinations visa-free. This was followed by the Syrian passport at 29 destinations, the Iraqi passport at 31 destinations and the Pakistani and Yemeni passports at 34 destinations. Among African countries, the Somali passport is the weakest passport according to the index.

Worked examples

Example 1 — a first encounter with Henley Passport Index

Start with the simplest possible case. Write down what Henley Passport Index claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In mathematics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Henley Passport Index before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Henley Passport Index ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Henley Passport Index

In research
Henley Passport Index appears in mathematics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Henley Passport Index in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Henley Passport Index is common in secondary-school and first-year university syllabi. It links to neighbouring topics Index numbers, International travel documents, Passports, so understanding it makes those chapters shorter.
In everyday life
Look for Henley Passport Index outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
