What is an IGO?

An International Government Organization (IGO) is generally a formal, ongoing structure established by agreement between members from three or more countries with the aim of pursuing the common interests of the membership. An IGO has international aims and goals, is often treaty-based, has a headquarters with officers, and has a nonprofit financial apparatus based on dues from its members.

Examples include such organizations as the United Nations, NATO, and the European Union. IGO imformation is an important resource for statistics, international policy, research, and guidelines/standards/specifications.

The number of IGOs is increasing due to globalization. The exact count is hard to ascertain, but IGOs number in the thousands.
