CIA reliable source

The CIA factbook is NOT a reliable source. Apart from the fact that the article now uses the CIA factbook for the vast majority of sources, most of the figures published in the factbook could easily have been plucked out of thin air. They have no source. For example a figure of 90% of Norwegians being Christian is clearly ridiculous and is widely inaccurate. In that case the Eurobarometer figure is much more sensible in terms of real world number. 

Let's not forget that that the CIA is the USA Central Intelligence Agency. It is a politically biased body. We we say figures from, for example, the Russian Intelligence agency, Iranian Intelligence Agency,Chinese Intelligence agency as being reliable? No, So why the American intelligence agency.

In fact pretty much every references in this article is now the US CIA Factbook or the US Department of State. Wikipedia is never going to be taken seriously with this kind of bias. This is simply unencyclopedic
