The world has a population of around eight billion people. It is estimated that up to 7,000 different languages are spoken around the globe.

Ninety percent of these languages are used by less than 100,000 people, however.

Languages are grouped into families that share a common ancestry. For example, English is related to German and Dutch, and they are all part of the Indo-European family of languages.

These also include Romance languages, such as French, Spanish and Italian, which come from Latin.

Perhaps one of the most interesting facts is that in only two of the countries on the list is English the most popular second language.
