This publication aims to provide a statistical overview on informality by applying a harmonized definition of informal employment and employment in the informal sector to micro data for more than 100 countries representing more than 90 per cent of the world’s employed population. The estimates are based on a common set of standardized criteria to determine informal employment and employment in the informal sector as the main job. The estimates are comparable across developed and developing countries and regions, but the ILO’s country estimates may differ from national ones when they exist. This edition also provides global and regional estimates for 2016 based on percentages calculated from the latest available data.
