Below is a List of languages by number of native speakers.
Over half the world's population speaks the 15 most used native languages. They are listed here. They are from the Swedish Nationalencyklopedin (2007, 2010).
The distinction between language and dialect is often not clear. Some mutually intelligible versions have been unified. These include Indonesian and Malay; Croatian, Bosnian, and Serbian. It does not include standard Hindi and Urdu. Hindustani has been divided here into the sociolinguistic units of Hindi and Urdu, but at least 100 million speakers of some Hindi dialects are not counted below.
