Wikipedia has a page called:

An NGO is a non-governmental organization, such as Doctors Without Borders, Human Rights Watch, Oxfam, WIRE AFRICA. World Social Forum, and WWF.

There are about two million NGOs in the United States and almost as many in India. Several hundred new NGOs are created every year in Kenya, and other African countries have growing numbers too.

A recent trend is to replace the somewhat negative term "non-governmental organization" with a more positively descriptive name such as "civil society organization" ("CSO").
