In 2015, the world committed to ending all forms of child labour by 2025. That goal has not been met. Today, nearly 138 million children remain trapped in child labour, according to the latest estimates from UNICEF and the ILO. These estimates draw on data from 107 countries and reflect major advances in measurement and national monitoring over the past two decades. Yet serious gaps remain: too few countries systematically integrate child labour into their national statistical systems, and coverage varies widely across regions. Nearly half of the world’s countries still lack timely, comparable data. Ending child labour requires more than commitment — it demands robust, consistent data to track progress, identify gaps and drive effective action.
