A stateless person is not recognised as a citizen by any state.
UNHCR estimates that statelessness affects at least 10 million people worldwide, with the highest concentration of stateless persons in the Asia-Pacific region.
Populations who are stateless, or at risk of statelessness, often have limited or no access to basic human rights such as education, employment, housing, and health services.
They are at a heightened risk of exploitation, human trafficking, arrest and arbitrary detention because they have difficulty proving who they are or links to a country of origin.
Stateless people, and those at risk of statelessness, are also often unable to pay taxes, buy and sell property, open a bank account, legally marry, or register a birth or death. Statelessness can also be a cause and consequence of forced migration.
