Non-governmental organization (NGO) is a term that has become widely accepted as referring to a legally constituted, non-governmental organization created by natural or legal persons with no participation or representation of any government. In the cases in which NGOs are funded totally or partially by governments, the NGO maintains its non-governmental status and excludes government representatives from membership in the organization. Unlike the term intergovernmental organization, "non-governmental organization" is a term in general use but is not a legal definition. In many jurisdictions these types of organization are defined as "civil society organizations" or referred to by other names.
The number of internationally operating NGOs is estimated at 40,000. National numbers are even higher: Russia has 277,000 NGOs. India is estimated to have between 1 million and 2 million NGOs.
