The rankings are available for 169 countries at this site. The rankings are made each year. Canada has moved down from 4th to 8th since the 2009 rankings.
The top five are Norway, Australia, New Zealand, United States, and Ireland. One might think that the effects of the recession might cause Ireland and the U.S. to move down the list a bit. It is not clear how much moving up or down the list means because all are still in the very high development range.
Norway is oil rich with a life expectancy of 81 years and an average annual income of 58,810 dollars, plus an average 12.6 years of education. Norway also has an excellent health care system. Norway has topped the list in all but two years since 2001.
At the very bottom of the Index was Zimbabwe run by Mugabe with an aged iron fist. Other African countries such as Mozambique, Burundi, Niger, and the Congo were also near the bottom. In Zimbabwe life expectancy is just 47 year and annual income 176 dollars. Zimbabwe has been last for the last five years. Countries such as Congo and Zimbabwe have seen their values drop below 1970 values because of such problems as conflict, AIDs, and mismanagement.
Many nations have moved up because of economic growth such as China, Indonesia and South Korea. Nevertheless China is still 89th which is in the High rather than Very High development group. Russia at 65th and even Iran at 70th are still better than China.
Countries of concern because of terrorism are often among the lowest group. Yemen is 133 and Afghanistan is even lower at 135th.
