A cooperative (also known as co-operative, co-op, or coop) is an autonomous association of people united voluntarily to meet their common economic, social and cultural needs and aspirations through a jointly owned and democratically controlled business. Cooperatives include non-profit community organizations and businesses that are owned and managed by the people who use their services (a consumer cooperative); by the people who work there (a worker cooperative); by the people who live there (a housing cooperative); hybrids such as worker cooperatives that are also consumer cooperatives or credit unions; multi-stakeholder cooperatives such as those that bring together civil society and local actors to deliver community needs; and second and third tier cooperatives whose members are other cooperatives. It was estimated that in 2012 approximately one billion people were members of at least one cooperative and that the turnover of the largest three hundred cooperatives in the world reached $2.2 trillion – which, if they were to be a country, it would make them the seventh largest.
In short, a co-op can be defined as "a jointly owned enterprise engaging in the production or distribution of goods or the supplying of services, operated by its members for their mutual benefit, typically organized by consumers or farmers." Cooperative businesses are typically more economically resilient than many other forms of enterprise, with twice the number of co-operatives (80%) surviving their first five years compared with other business ownership models (41%). Cooperatives frequently have social goals which they aim to accomplish by investing a proportion of trading profits back into their communities. As an example of this, in 2013, retail co-operatives in the UK invested 6.9% of their pre-tax profits in the communities in which they trade as compared with 2.4% for other rival supermarkets.
The International Co-operative Alliance was the first international association formed by the cooperative movement. It includes the World Council of Credit Unions. A second organization was formed later in Germany, the International Raiffeisen Union. In the United States, the National Cooperative Business Association (NCBA) serves as the sector's oldest national membership association. It is dedicated to ensuring that cooperative businesses have the same opportunities as other businesses operating in the country and that consumers have access to cooperatives in the marketplace. A U.S. National Cooperative Bank was formed in the 1970s. By 2004, a new association focused on worker co-ops was founded, the United States Federation of Worker Cooperatives.
