I want to know the answer to the following question:
What percentage of Swiss people claimed no church affiliation in 2012?
All the background I'm provided with is that "21.4% in 2012 declared themselves as unchurched i.e. not affiliated with any church or other religious body (Agnostic, Atheist, or just not related to any official religion).". Is that enough to answer the question?
Answer: yes
