Membership of the United Nations Security Council is held by the five permanent members and ten elected, non-permanent members. Prior to 1966, there were six elected members, while the permanent members have in essence not changed since the creation of the United Nations in 1945, apart from the representation of China. Elected members hold their place on the Council for a two-year term, and half of these places are contested each year. To ensure geographical continuity, a certain number of members is allocated for each of the five UN regional groupings.
*During the 2016 Security Council elections, Italy and the Netherlands agreed to split a two-year term, in which Italy would serve from 1 January 2017 to 31 December 2017 and the Netherlands would subsequently serve from 1 January 2018 to 31 December 2018.African Group: 3 members
Asia-Pacific Group: 2 members
Eastern European Group (CEIT, or Countries with Economies in Transition): 1 member
Latin American and Caribbean Group (GRULAC): 2 members
Western European and Others Group (WEOG): 2 members; at least one of these must be from Western Europe
In addition, one of the non-permanent members of the council is an Arab country, alternately from the African or Asia-Pacific groups. This rule was added to the system in 1967 for it to be applied beginning with 1968.
Each year the UN General Assembly elects five new members for a two-year term; these elections always begin in October of the year, and continue until the two-thirds majority for the number of countries for each region has been reached. Re-election is allowed, but the term must not be consecutive.Electoral timetable
* The representative of Arab nations alternates between these two elected spaces.
From 1946 to 1965, the security council included six non-permanent members. The regional grouping at that time was:Latin America: 2 members
Commonwealth of Nations: 1 member
Eastern Europe: 1 member
Middle East: 1 member
Western Europe: 1 member
There were some exceptions to this grouping: Liberia took the place of a Western European country in 1961; the Ivory Coast substituted a member of the Commonwealth in 1964–1965; and the Eastern Europe group included Asian countries from 1956.
As part of a proposed expansion of the Security Council, Brazil, Germany, India and Japan, collectively the Group of 4 or G4 nations, are seeking permanent representation on this body.
