Civil registry

Civil registration is the system by which a government records the vital events of its citizens and residents. The resulting repository or database is called civil register, and the office responsible for receiving registrations is often called the registrar, registry, or population registry. The primary purpose of civil registration is to create a legal document that can be used to establish and protect the rights of individuals. A secondary purpose is to create a data source for the compilation of vital statistics. In most countries, there is a legal requirement to notify the relevant authority of certain life events, such as births, marriages and death. The first country to establish a nationwide population register was Sweden in 1631, which was organized by the Church of Sweden but on the demand of The Crown.

The United Nations defines civil registration as "the continuous, permanent, compulsory and universal recording of the occurrence and characteristics of vital events pertaining to the population as provided through decree or regulation in accordance with the legal requirements of a country. Civil registration is carried out primarily for the purpose of establishing the legal documents provided by the law. These records are also a main source of vital statistics. Complete coverage, accuracy and timeliness of civil registration are essential for quality vital statistics."
