Atlas of the World's Languages in Danger

The Atlas of the World's Languages in Danger is an online tool published by UNESCO (United Nations Educational, Scientific and Cultural Organization) that identifies and classifies endangered and extinct languages.

The Atlas of the World's Languages in Danger classifies languages into six different categories.

• Extinct (EX): There are no speakers left (included if extinct since the 1950s)
• Critically endangered (CR): The youngest speakers are grandparents and older, and they speak the language partially and infrequently
• Severely endangered (SE): Language is spoken by grandparents and older generations; while the parent generation may understand it, they do not speak it to children or among themselves
• Definitely endangered (DE): Children no longer learn the language as mother tongue in the home
• Vulnerable (VU): Most children speak the language, but it may be restricted to certain domains (e.g., home)
• Safe (NE): Language is spoken by all generation; inter-generational transmission is uninterrupted
