The Expanded Graded Intergenerational Disruption Scale (EGIDS), developed by Lewis and Simons (2010) as an expansion of Joshua Fishman's GIDS, measures a language's status in terms of endangerment or development.
The table below shows the various levels on the scale:
The Laz people, or Lazi (Laz: ლაზი Lazi; Georgian: ლაზი, lazi; or ჭანი, ch'ani; Turkish: Laz), are a Kartvelian ethnic group native to the South Caucasus, who mainly live in Black Sea coastal regions of Turkey and Georgia. They traditionally speak the Laz language (which is a member of the Kartvelian language family) but have experienced a rapid language shift to Turkish.
Of the 103,900 ethnic Laz in Turkey, only around 20,000 speak Laz and the language is classified as threatened (6b) in Turkey and shifting (7) in Georgia on the Expanded Graded Intergenerational Disruption Scale.
Aleut (/ˈæliuːt/ AL-ee-oot) or Unangam Tunuu is the language spoken by the Aleut living in the Aleutian Islands, Pribilof Islands, Commander Islands, and the Alaska Peninsula (in Aleut Alaxsxa, the origin of the state name Alaska). Aleut is the sole language in the Aleut branch of the Eskimo–Aleut language family. The Aleut language consists of three dialects, including Unalaska (Eastern Aleut), Atka/Atkan (Atka Aleut), and Attu/Attuan (Western Aleut, now extinct).
Various sources estimate there are fewer than 100 to 150 remaining active Aleut speakers. Because of this, Eastern and Atkan Aleut are classified as "critically endangered and extinct" and have an Expanded Graded Intergenerational Disruption Scale (EGIDS) rating of 7. The task of revitalizing Aleut has largely been left to local government and community organizations. The overwhelming majority of schools in the historically Aleut-speaking regions lack any language/culture courses in their curriculum, and those that do fail to produce fluent or even proficient speakers.
