Why aren all the countries included in the GDI, GEM, and HPI?
Lack of data is a particular constraint in monitoring gender disparity and poverty. Coverage of the GDI in HDR 2009 is limited to 155countries, GEM to 109 countries, and the HPI-1 to 135 developing and transition countries and HPI-2 to 25 high-income OECD countries (see also “Why isn’t HDI compiled for all UN member countries?”).
