Is the HDI comparable across editions of the HDR?

Due to revisions to the data series for some or all of the components of the HDI, changes in the HDI methodology, or variations in the country coverage, the HDI values and ranks presented in the 1990 through 2009 editions of the Report are not directly comparable. The year-to-year changes in the index often reflect data improvement, instead of real increase or decrease in the level of human development (see PDF Inline (GIF) Readers' guide [390 KB]).

The Human Development Report Offices strongly advises against constructing HDI trend analysis based on the HDI published in different editions of the Report. For the most up-to-date HDI trend data based on consistent country coverage, methodology and data, please refer to PDF Inline (GIF) Table G HDR 2009 [93 KB]  Human Development Index Trends.
