Cooperation is a way of living, a philosophy of life, and has been the very basis for human civilization. The roots of formal Cooperation can be traced to ancient times. Cooperatives are believed to enable the rural and urban poor to meet their economic, social, and cultural needs collectively, which is often difficult to achieve individually.According to the findings of this study, there is an overall increasing trend in the Union's membership and efficiency of financial performance.
