Which is the richest and poores according to GDP per capita?

The most reliable source of such information would be provided by the Worldbank. In recent years they have moved away from reporting GDP per capita and instead report GNI (Gross National Income) per capita. For 2006 the rankings are listed in the following file: http://siteresources.worldbank.org/DATASTATISTICS/Resources/GNIPC.pdf Here Luxembourg tops the list with US $76,040 (yearly). However there is an important fact to take into consideration. About 1/3 of this income belongs to commuting residents of surrounding countries. This means that the GNI per capita of actual residents of Luxembourg would be closer to 50,000 or so. If taking the above into consideration Bermuda is assumed to take the top spot based on historic numbers (No actual data is available for 2006). Of course, Bermuda has a tiny population of only 64,000 which is no more than a medium sized town. Of countries with larger populations, say a million or more, Norway would take the top spot with $66,530 for 2006. At the poor end of the spectrum it is a bit more difficult to determine, due to the lack of data from many of the poorest countries. The country with the lowest reported GNI per capita on the Worldbank list is Burundi with $100.
