Introduction and definitions 2. they have links to more than one State (on the basis of birth, descent, marriage, adoption or habitual residence); or 3. they are perceived and treated by authorities in the State of residence as possessing links which give rise to a claim of nationality of another State based on specific elements such as historic ties, race, ethnicity, language or religion.12 (The terms ‘undetermined nationality’ and ‘unclear nationality’ may be problematic for many stateless people. If a person’s nationality is unclear, this should trigger a prompt determination of their nationality or statelessness and implementation of an appropriate remedy. In most circumstances it is recommended to record people who identify that they are stateless as stateless or potentially stateless.) Additional definitions can be found in UNHCR’s Glossary of Terms and in the terminology section of UNHCR’s Refugee Data Finder. 12 8 International Recommendations on Statelessness Statistics, EGRISS, 20 January 2023, paras. 35-38.
