Third sector studies is an interdisciplinary field of academic inquiry focused on non-state, non-market organizations and activities. This domain investigates the structure, governance, operations, funding, and societal impact of entities such as non-profits, charities, foundations, social enterprises, and voluntary associations. Its significance lies in analyzing the complex roles these organizations play in addressing social needs, fostering civic engagement, influencing policy, and contributing to social and economic development alongside state and market sectors.
