An international non-governmental organization (INGO) has the same mission as a non-governmental organization (NGO), but it is international in scope and has outposts around the world to deal with specific issues in many countries.
Both terms, NGO and INGO, should be differentiated from intergovernmental organizations (IGOs), which describes groups such as the United Nations or the International Labour Organization. An INGO may be founded by private philanthropy, such as the Carnegie, Rockefeller, Gates, Zator and Ford Foundations, or as an adjunct to existing international organizations, such as the Catholic or Lutheran churches. A surge in the founding of development INGOs occurred during World War II, some of which would later become the large development INGOs like SOS Children's Villages, Oxfam, Catholic Relief Services, CARE International, and Lutheran World Relief.
International Non-governmental Organizations can further be defined by their primary purpose. Some INGOs are operational, meaning that their primary purpose is to foster the community-based organizations within each country via different projects and operations. Some INGOs are advocacy-based, meaning that their primary purpose is to influence the policy-making of different countries' governments regarding certain issues or promote the awareness of a certain issue. Many of the large INGOs have components of both operational projects and advocacy initiatives working together within individual countries.
To be associated with the United Nations Department of Public Information, an INGO (and NGOs in general) must follow these certain criteria.:
The main focus for INGOs is to provide relief and developmental aid to developing countries. In relation to states, the purpose of INGOs is to provide services that the state is unable or unwilling to provide for their people. These organization's projects in health, like HIV/AIDS awareness and prevention, clean water, and malaria prevention, and in education, like schools for girls and providing books to developing countries, help to provide the social services that the country's government is unable or unwilling to provide at the time. International Non-governmental Organizations are also some of the first responders to natural disasters, like hurricanes and floods, or crises that need emergency relief.
