Firstly, the first line dedicated on the topic in question, is this:

So as I stated in my post, this is not exactly reliable information (no worries, I will find the statistical data I need for myself).
Secondly, there is a lot of confusing and conflicting information, heres why:
Religion in Norway is overwhelmingly Protestant (Evangelical-Lutheran) with 82.7% belonging to the state Evangelical Lutheran Church of Norway.[1] Early Norwegians, like all of the people of Scandinavia, were pagans believing in Norse mythology; the Sámi having a shamanistic religion. Due to the efforts of Christian missionaries, Norway was gradually Christianized in a process starting at approximately 1000 AD and which was substantially finished by 1150AD. Prior to the Reformation, Norwegians were part of the Catholic Church with the conversion to Protestantism occurring in 1536. Islam is now the second largest religion due to recent migration trends although the census shows that there are more people with no religious beliefs.[citation needed]
According to the most recent Eurobarometer Poll 2005,[2]
32% of Norwegian citizens responded that “they believe there is a God”.
47% answered that “they believe there is some sort of spirit or life force”.
**17% answered that “they do not believe there is any sort of spirit, God, or life force”. **
4% answered that they “do not know”.
Phil Zuckerman, an Associate Professor of Sociology at Pitzer College writes of several academic sources who have in recent years estimated atheism rates in Norway at 72%".[3]
Now, let me get this straight, 82.7% are stated to belong to the State Evangelical Lutheran Church of Norway. But wait, Phil Zuckerman states that atheist rates in Norway are at 72% (didn’t you say 68% earlier, oh, you added 47and 17 and 4 to give you 68%). And yet from the data, I’m told only 17% are actually atheists. This is confusing.

Please in future, use credible sources. God bless.
P.S. I want to know where you got your info concerning China, please.
