United Nations System
There are 15 members of the Security Council, consisting of five veto-wielding permanent members (China, France, Russia, the United Kingdom, and the United States) and 10 elected non-permanent members with two-year terms. This basic structure is set out in Chapter V of the UN Charter. Security Council members must always be present at UN headquarters in New York so that the Security Council can meet at any time.
United Nations Human Rights Council
The UNHRC has 47 members, selected each year by the UN General Assembly for staggered three-year terms on a regional group basis. No member may occupy a seat for more than two consecutive three-year terms. The seats are distributed among the UN's regional groups as follows: 13 for Africa, 13 for Asia, six for Eastern Europe, eight for Latin America and the Caribbean (GRULAC), and seven for the Western European and Others Group (WEOG).
