Statelessness is the condition whereby an individual is not considered a national by any country. Stateless people are denied basic rights, such as access to employment, housing, education, healthcare, and pensions, and they may be unable to vote, own property, open a bank account, or legally register a marriage or birth. They may also be vulnerable to arbitrary treatment and human trafficking. In at least 30 states, women cannot pass their nationality on to their children. In these countries, if a child's father is foreign, stateless, or absent, the child usually becomes stateless. Estimates of the number of stateless people are inherently imprecise because few countries have procedures to identify them; the UN approximates that there are 12 million stateless people worldwide. Stateless people are counted in a country’s overall population figure if they have lived there for a year.
