[1] Each nationality receives an aggregated score based on economic strength, human development, ease of travel, political stability and overseas employment opportunities for their citizens.

The phenomenon of being a native of any country was described as 'a birthright lottery' by Ayelet Shachar, Professor of Law, Political Science, and Global Affairs at the University of Toronto.

[3] At the same time, the QNI shows that nationalities diverge greatly in their practical value, which is not always parallel with the characteristics of those countries, such as economic power or level of human development.

[4][5][6][7] The QNI takes a quantitative approach to determine the value of a nationality based on seven parameters, comprising both internal value (40%) and external value (60%).

The internal factors present the quality of life and opportunities for personal growth within the country of origin of the holder of nationality.

[12][13] Economic strength of a nationality is based on the Gross domestic product (GDP) at Purchasing power parity (PPP) of each country.

[17] External factors identify the quality and diversity of opportunities the holder of a nationality can pursue outside their country of origin.

[18] Diversity of travel freedom is based on how many destinations the holder of a particular nationality can visit without a visa or with a visa-on-arrival for short-term tourism or business purposes.

[21] Diversity of settlement freedom is based on the number of foreign countries in which the holder of a nationality can freely settle for at least 360 days with automatic access to work there.
