Enter an answer into the box. Guess in which countries of 57 are the populations least inclined to say they are religious. The hint is the percent religious and the dominant religion(s) of that country.
I can assure you that Estonia would be among the 20 least religious countries by every serious source. Also, finding Turkey here is simply unbelievable.
The list came from a survey of 57 countries which I can no longer find. In a complete survey, Estonia would easily make the top 10. In urban Turkey, most people are nominal Muslims in the same way Italians are nominal Catholics. The current Islamic party receives its support from rural areas. My guess is the survey was biased toward urban residents.
