Did the HDI rankings change for many countries in 2013?

Based on the consistent data series that were available on 15 November 2013, there are few countries with changed ranks between 2012 and 2013. The HDI values for 2012 and 2013 are given in Table 1 of Statistical Annex. The HDI trends since 1980 are given in Table 2. In this table we also provide the change in ranks between 2008 and 2013.

We advise users of the HDR not to compare the results from different Reports, but to use the consistent data given in Table 2 of the latest report. The consistent data are based on the latest data revisions and are obtained using the same methodology. The effect of change in achievements (improvement or declining) in human development indicators of health, education and living standards is captured by comparing the HDIs obtained from the consistent data series.

The difference between values published in two different Reports is the combined effect of data revision, change in methodology, and the change in achievements in indicators.
