Thanks to Berk Ülsoy, I learned about a very interesting information visualization web site that provides the reader with valuable statistics: The Atlas of European Values. The web site lets you to set many parameters and then compare different demographic groups. Below you can see an example that shows the percentage of people who rank Europe as the first or second most important group to which they belong based on their income (low versus high):Apparently, rich Europeans in general think in terms of a more global citizenship, whereas Europeans with lower income does not consider belonging to Europe as their most important identity. The difference seems to be especially striking for countries such as France, Switzerland, Italy, Germany, Belgium, and Netherlands.
