Monitoring progress and determining whether the goal of ending poverty by 2030 is met crucially depends on how poverty is measured. In particular, it crucially depends on the global poverty line and how the line is adjusted over time. A special issue of the Journal of Economic Inequality, which this paper introduces, is dedicated to present alternative approaches to determine the global poverty line (or, more precisely, poverty lines) in order to measure the extent and evolution of extreme poverty in the developing world. In this special issue, the authors also carefully assess the merits and shortcomings of each of these approaches.
