The World of Work is continuously evolving, perhaps never more quickly than in recent years. This means that statistical standards need to evolve as well to capture the complex realities of the world of work. Informality remains a key concern of the Decent Work Agenda and the 2030 Agenda for Sustainable Development (the share of informal employment is part of the indicators selected to measure progress towards the Sustainable Development Goals, as SDG indicator 8.3.1). Addressing informality is also critical for women's economic empowerment and gender equality. The 21st International Conference for Labour Statisticians (ICLS) adopted in October 2023 A New Standard on the Informal Economy. The new standard improves the coverage, usefulness, and comparability of informality statistics and sheds light on who are those in the informal economy, working conditions and contextual vulnerabilities in the informal economy, which employs two billion people, or about 60 percent of the world's employed population1. In many countries, informal employment and the informal sector represent a significant part of the economy and labour market and plays a major role in production, employment creation and income generation. The debate concerning strategies towards formalization of the informal economy gained new momentum worldwide, after ILO's constituents adopted, at the International Labour Conference in June 2015, the Recommendation 204 (R204), the first international standard focusing exclusively on the informal economy and the strategies to adopt for the transition from the informal to the formal economy. Measuring and analysing informality remains a challenge for many countries that hinders policy-making to address the consequences of informality and facilitate transitions to formality. The lack of data and statistics on the informal economy also means that its economic contribution is not taken into account.. Bearing in mind the growing demand from countries to better understand the functioning of the informal economy and the measurement of informality, the International Training Centre of the ILO in Turin (ITCILO) in close collaboration with the ILO Department of Statistics are proud to offer the face-to-face training "Measuring informality: Introducing the new statistical standards on the Informal economy."
