This document summarizes the development of cooperative statistics guidelines by the International Labour Organization (ILO). It discusses the need for reliable cooperative statistics given their significant economic contributions. An ILO resolution recognized the need for statistics on cooperatives in all countries. As a result, the ILO carried out studies in six countries including the Philippines to develop a common framework. The guidelines were finalized in 2018 and aim to assess cooperatives' economic impacts through various metrics like employment and earnings. Challenges remain in collecting comprehensive cooperative data from all countries.
