The 2011 Human Development Report argues that the urgent global challenges of sustainability and equity must be addressed together – and identifies policies on the national and global level that could spur mutually reinforcing progress towards these interlinked goals. Bold action is needed on both fronts, the Report contends, if the recent human development progress for most of the world’s poor majority is to be sustained, for the benefit of future generations as well as for those living today. The 2011 Report also features the 2011 Human Development Index (HDI) and updated editions of the complementary indices introduced in the 20th anniversary Report in 2010: the Inequality-Adjusted HDI, the Gender Inequality Index, and the Multidimensional Poverty Index
