Where can I get information about regional groups?

"While there is no classification based upon formal membership in a geographical group, Member States are characterized in [...] geographic patterns as African States, Asian States, Eastern European States, Latin American States, and Western European and other States.

In the practice of the United Nations, regional groups corresponding to the aforementioned geographic patterns have evolved as informal arrangements among Member States. The latter groups are based entirely on the agreement of Member States and serve as a mechanism for consultation and coordination among them, particularly on matters relating to elections and candidatures, in the light of the requirement for equitable geographical balance or regional rotation and distribution in United Nations organs and bodies. The members of certain regional groups also use the groups for discussion and consultation on policy issues."
(UN Juridical Yearbook 1996, page 442)

Below is a list of the regional groups as provided by the UN Department of General Assembly and Conference Management:

• African States
• Asia-Pacific States
• Eastern European States
• Latin American and Caribbean States
• Western European and other States

The full list of countries and regional groups can be found on the website of the UN Department of General Assembly and Conference Management.

Chairs of the regional groups rotate monthly and are listed in the General Information section of the Journal of the United Nations.

The origins and development of UN electoral groups is outlined in the United Nations University (UNU) publication, What is Equitable Geographic Representation in the Twenty-first Century: Report of a seminar held by the International Peace Academy and the United Nations University, 26 March 1999, New York, USA
