How many countries are included in the 2014 HDI?

The 2014 HDI covers 188 countries, compared to 187 countries covered during 2011-2013. This year it became possible to compute the HDI value for South Sudan. The wide coverage is the result of efforts by the Human Development Report Office (HDRO) to work with UN agencies and the World Bank, who provide internationally standardized data and also with national statistical agencies to obtain required development indicators for the HDI. For a full explanation of the results and methodology of the 2014 HDI and other composite indexes in the 2015 Human Development Report, please see the Technical Notes 1-5.
