Explanatory note on 2011 HDR composite indices

02 Nov 2011

Introduction

The 2011 Human Development Report presents 2011 Human Development Index (HDI) values and ranks for 187 countries and UN-recognized territories, along with the Inequality-adjusted HDI for 134 countries, the Gender Inequality Index for 146 countries, and the Multidimensional Poverty Index for 109 countries.

Country rankings and values in the annual Human Development Index (HDI) are kept under strict embargo until the global launch and worldwide electronic release of the Human Development Report.  The 2011 Report will be launched globally in November 2011.

It is misleading to compare values and rankings with those of previously published reports, because the underlying data and methods have changed, as well as the number of countries included in the HDI. The 187 countries ranked in the 2011 HDI represents a significant increase from the 169 countries included in  the 2010 Index, when key indicators for many countries were unavailable.  

Readers are advised in the Report to assess progress in HDI values by referring to Table 2 (‘Human Development Index Trends’) in the Statistical Annex of the report. Table 2 is based on consistent indicators, methodology and time-series data and thus shows real changes in values and ranks over time reflecting the actual progress countries have made.

For further details on how each index is calculated please refer to Technical Notes 1-4 in the 2011 Report and the associated background papers available on the Human Development Report website.
