About how many people speak Caucasian languages?

There are approximately 8 million speakers of Caucasian languages.

These indigenous languages are concentrated in the Caucasus region between the Black and Caspian seas, and their communities vary significantly in size, ranging from small groups of only a few hundred people to large national populations numbering in the millions.1

The Caucasian languages are categorized into three distinct families:
* Northwest Caucasian (Abkhazo-Adyghian)
* Northeast Caucasian (Nakho-Dagestanian)
* South Caucasian (Kartvelian or Iberian)1

For example, the South Caucasian family, which includes Georgian, had approximately 4.2 million speakers as of the mid-1990s. The remaining speakers are distributed among various groups within the North Caucasus, such as the Nakh and Dagestanian language groups.23
