In a study conducted by the European Institute of Business Administration, Kai Chan created a Power Language Index (PLI) that ranked languages based on five opportunities provided by language comprehension: the ability to travel widely, the ability to earn a livelihood, the ability to communicate with others, the ability to acquire knowledge and consume media, and the ability to engage in diplomacy.[8] Within these five sections, Chan used 20 indicators such as the GDP associated with countries that speak a certain language, the amount of land area where a language is spoken, and amount of internet/media content associated with a language to rank them.
