In contrast, the poverty figures estimated by ECLAC are generated with the aim of achieving the greatest possible comparability for various analytical purposes, and, given their different objectives and uses, they certainly do not seek to replace the national figures to describe poverty levels and trends in each country. As both data sets display similar trends, it is considered appropriate to use the national figures to describe the behaviour of poverty in each country. Meanwhile, comparable poverty measurements are used to construct regional aggregates and analyse the drivers of poverty and how different population groups are affected by it. Thus, ECLAC data contribute to a regional diagnosis that prioritizes evidence-based analysis on poverty-reduction policies.
