Voluntary organizations are groups organized on the basis of voluntary membership to accomplish common goals or interests of members. They can be formed for purposes such as trade associations, unions, cultural activities, and avoiding government monopoly. Some key objectives of voluntary organizations are to meet uncovered societal needs, improve national solidarity, and avoid concentration of power in government hands. Examples of voluntary organizations in India before independence include Ramkrishna Mission and Dharma Samaj, while after independence include Infosys Foundation, Tata Trust, and Azim Premji Foundation. Common types of voluntary organizations globally include charities, foundations, social welfare and advocacy groups, faith-based organizations, community groups, and recreational sports organizations.
