Voluntary sector
The voluntary sector or community sector (also non-profit sector or "not-for-profit" sector) is the duty of social activity undertaken by organizations that are not for-profit and non-governmental. This sector is also called the third sector,
in contrast to the public sector and the private sector. Civic sector or social sector are other terms for the sector, emphasizing its relationship to civil society. Given the diversity of organizations that comprise the sector, Peter Frumkin prefers "non-profit and voluntary sector".
Country-specific
France
Discourse on the "third sector" began in the 1970s in France as a result of the crisis in the welfare state.
United Kingdom
The Cabinet Office of the British government until 2010 had an Office of the Third Sector that defined the "third sector" as "the place between State and (the) private sector." The Conservative/Liberal Democrat Coalition Government renamed the department the Office for Civil Society. The term third sector has now been replaced in Government usage by the term Civil Society or more usually the term Big Society, which was devised by political advisers and which featured prominently in the Conservative Party's 2010 election campaign.
