Each year the United Nations publishes the Human Development Report, which provides information on the standard of living in nearly every country in the world. The Report includes data on real GDP per person, but also contains a broader measure of the standard of living called the Human Development Index (HDI). The HDI combines data on real GDP per person with data on life expectancy at birth, adult literacy and school enrollment. The following table shows values for real GDP per person and the HDI for several countries. Prepare one list ranking countries from highest real GDP per person to lowest, and another list ranking countries from highest HDI to lowest. Briefly discuss possible reasons for any differences in the rankings of the countries in your two lists. (All values in the table are for the year 2003).
