Do all persons have citizenship?
No. It has been estimated that there are currently about 15 million stateless persons worldwide. From the Nubian people of Kenya to residents of the Dominican Republic of Haitian descent, statelessness is a global phenomenon affecting the health, economic well-being, and human security of the individuals, families, and groups involved.
The Open Society Justice Initiative has produced a series of documentaries on the issue, the introduction to which can be viewed below. From the description:
Although some stateless people are refugees, many have never crossed a border or left their country of birth. Although the problems related to statelessness may manifest themselves differently, at the root is a group of people who have been denied a legal identity.
A stateless person is not recognized as a citizen by any state. Citizenship enables you not only to vote, hold public office, and exit and enter a country freely, but also to obtain housing, health care, employment, and education. Citizenship is necessary in order to live a decent human life. Stateless people are denied that right.
