Sustainability and Equity: A Better Future for All
Explanatory note on 2011 HDR composite indices
HDI values and rank changes in the 2011 Human Development Report
The 2011 Human Development Report presents 2011 Human Development Index (HDI) values and ranks for 187 countries and UN-recognized territories, along with theInequality-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 ismisleading 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 theReport 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 TechnicalNotes 1-4 in the 2011 Report and the associated background papers available on the Human Development Report website.
Human Development Index (HDI)
The HDI is a summary measure for assessing long-term progress in three basic dimensions of human development: a long and healthy life, access to knowledge and a decent standard of living. As in the 2010 HDR a long and healthy life is measured bylife expectancy, access to knowledge is measured by: i) mean years of adult education, which is the average number of years of education received in a life-time by people aged 25 years and older; and ii) expected years of schooling for children of school-entrance age, which is the total number of years of schooling a child of school-entrance age can expect to receive if prevailing patterns ofage-specific enrolment rates stay the same throughout the child's life. Standard of living is measured by Gross National Income (GNI) per capita expressed in constant 2005 PPP$. To ensure as much cross-country comparability as possible, the HDI is based primarily on international data from the UN Population Division, the UNESCO Institute for Statistics (UIS) and the World Bank. As stated in theintroduction, the HDI values and ranks in this year’s report are not comparable to those in past reports (including the 2010 HDR) because of a number of revisions done to the component indicators by the mandated agencies. To allow for assessment of progress in HDIs, the 2011 report includes recalculated HDIs from 1980 to 2011.
Mexico’s HDI value and rank
Mexico’s HDI value for 2011 is 0.770—inthe high human development category—positioning the country at 57 out of 187 countries and territories. Between 1980 and 2011, Mexico’s HDI value increased from 0.593 to 0.770, an increase of 30.0 per cent or average annual increase of about 0.8 per cent. The rank of Mexico’s HDI for 2010 based on data available in 2011 and methods used in 2011 is 57 out of 187 countries. In the 2010 HDR, Mexico wasranked 56 out of 169 countries. However, 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. Table A reviews Mexico’s progress in each of the HDI indicators. Between 1980 and 2011, Mexico’s life expectancy at birth increased by 10.4 years, mean...
