While most countries across the world have deemed one, or more, languages to be their official language; others have had no language declared on a legal level and instead have a de facto national language. De facto means that the language is spoken by a majority of the country's population but it has not legally been declared the official language. This language bubble chart breaks down the 29 languages that have been deemed the official language of two or more countries, and each bubble contains the names of all of those countries.
The countries with de facto national languages were also included in their respective language. There is a world map that highlights where the 5 most widespread official languages are found, making up more than half of the world. Would you be surprised to find that English is the most widespread, and was found to be the official language of 55 countries and the de facto language of four?
