A majority of workers in the world are informally employed and contribute to economic and social development through market and non-market activities that are not protected, regulated, well-recognised or valued. This study provides an in-depth diagnosis of informality and the vulnerability prevailing in the informal economy. It explores new ideas to improve the lives of workers in the informal economy based on the ILO indicators of informality and the new OECD Key Indicators of Informality based on Individuals and their Household (KIIbIH).
