Providing empirical evidence that serves as the basis for establishing priorities in national and sub-national policies aimed at the prevention and elimination of child labour is one of the objectives of the Regional Initiative. For this reason, through joint work with the ILO Regional Office for Latin America and the Caribbean and ECLAC, they developed a tool with two methodologies: a) the Child Labour Risk Identification Model (CLRISK) and b) the Index of Vulnerability to Child Labour (IVTI-its acronym in Spanish), which - based on existing statistical information in the countries (surveys, censuses and/or administrative records) - allow, on the one hand, to identify the territories most vulnerable to child labour and, on the other, to estimate the weight of various associated factors in order to define which multi-sectoral actions are most effective to interrupt the trajectory of child labour and, in the medium term, to reduce the indicator in a sustained manner.
