NGOs, or non-governmental organisations, are citizen-founded organisations that assume social responsibility in specific subject areas without aiming to make a profit. Most NGOs take the legal form of an association.
NPOs, or non-profit organisations, pursue social, cultural or scientific objectives without seeking economic gain. They can be founded privately, i.e. as associations, or by the state, as social economy organisations. There is no standard definition for the term.
QUANGOs, or quasi non-governmental organisations, are a hybrid form straddling the public sector and NGO sector. They include organisations that largely work independently, perform state tasks and are mostly supported by public funds.
