I was asked a question:

"Are you saying that 25% of the people in Oslo are Muslim immigrants?2

Something like that, I know that about 14 years ago it was just below 20% and initial commentators when asked to speculate mentioned the 25% figure. Oslo is the largest centre of population in Norway with about 600,000 people but they are very spread out (Oslo holds two characteristics as a Capital City it has one of the smallest populations but in terms of size and area is one of the largest in Europe)
