Karte des Katholizismus auf dem Balkan

OK, how do you measure this? Only 15 % in BiH? And only 3.5 in Romania? As a Croat living in Romania, I call it bullshit map. Judging by seeing number of churches around, and knowing peop here, i say Romania is at least 7 %.

Catholicism is at 8-9% in Bosnia-Herzegovina now and at over 80% in Croatia.
