@Olivier5,
There are many more emigrants in GB than in Norway per capita. After all more people speak English and know about GB than speak Norwegian or have knowledge about Norway.
About 12% of the British population are non whites according to statistics and in Norway it is 5%.
These numbers might have changed as the information is from 2012.
GB also has a population which is ten times larger than Norway´s.
People from non Western countries have lately not even wanted to go to Norway - too strict and too little help.
