* Official Language: Khmer, the Cambodian language, is the official language of Cambodia. This means it's used in government, education, and media.
* Native Speakers: Estimates put the number of native Khmer speakers at around 15 million in Cambodia itself.
* Diaspora: A significant Cambodian diaspora exists globally, particularly in countries like the United States, France, and Thailand. This adds a significant number of Khmer speakers outside of Cambodia.
* Variations: Within Cambodia, there are regional variations in Khmer, and some smaller ethnic groups speak other languages.
Therefore, while we don't have a precise figure, it's safe to say that millions of people speak Cambodian worldwide.
