Article in law: articles refer to the consolidated version of the current citizenship law of a specific country, as provided at the profile page of each country, unless stated otherwise. Material conditions may be specified in lower level legislation, such as circulars or regulations. In contrast to Europe, the states in the Americas and the Caribbean frequently address citizenship in their Constitutions. The database uses 'Const' as a short-hand when referring to constitutional provisions.

Procedure: refers to the procedures for acquiring or losing citizenship. Please refer to the Citizenship Glossary for an explanation of the different procedures.

Conditions: refers to the conditions for acquiring or losing citizenship, in addition to the general condition stated in the description of each target group. Unless indicated otherwise a "person" refers to a person who has reached the age of majority and "residence" refers to legal residence only (as defined by national law).

Changes: refers to major changes in the citizenship legislation of a country. Generally changes since 1980 are covered and only the year of a change is indicated. For some countries the content of these changes is described in more detail. In future updates of the Database the goal is to do so for relevant changes in all countries included in the Database.
