Karsten, Thanks for your comments. You may want to see the Atlas of Global Development at http://data.worldbank.org/news/eatlas-of-global-development-released. Its electronic version is accessible from at http://www.app.collinsindicate.com/worldbankatlas-global/en which is a great resource to be used as a teaching tool. In addition, you can access our DataBank where you can access various databases; create your own queries which can be saved and used at a later time; and view results in table, chart and map formats. The DataBank can be accessed from http://databank.worldbank.org/ddp/home.do?Step=1&id=4. You can always send us an e-mail to email@example.com in case you have any questions.
