Is there evidence that the political debate on immigration and integration is becoming Europeanized? We could pick a few anecdotes either way, or we could do it systematically.
Here is a breakdown of the scope of the individuals or organizations making political claims over time. Claims are grouped into 5 years, and in all contexts the national (and sub-national) scope dominates — the maximum in the figure is 6.5%.
Also on figshare.
I note an upward trend in European claims between 2000-4 and 2005-9 in five countries, and downward trend in the two countries perhaps less closely integrated in the European Union.
