Comparative approaches. The maps offer the opportunity for multiple comparative approaches. Comparative approaches have been stressed to be of high relevance to realise a policy impact by PHR activities. They not only show differences, but give the idea that a status could be different and sometimes also about opportunities to change something. This can be a strong motivation for action and create political pressure. Also, they contribute to the legitimation for a redistribution of resources, e.g. between countries and regions. As far as European policies and member states are concerned, it seems to be necessary to support multilevel comparative approaches. Resources are redistributed at the European level and in line with the differences across Europe. But there are also relevant differences within Member States or regions of Member States. For example, differences within Germany should not be overseen in cause of the impressive differences especially between old and new EU Member States. The maps of the application can give a more general overview over EU Member States, a more detailed picture of the European regions. It is possible to look at the new Member states or old Member States only, or take a look at the differences within a Member State. This is of advantage because looking at differences across the whole European Union is informative while beside large differences between Member States there are also relevant regional differences within Member States. For policy making, looking at different levels and regional entities allows to set priorities for the different levels.
