You are not alone...
The sheer number of secular men and women on planet earth is unprecedented — according to the Pew Research Center’s latest estimates, there were over 1.1 billion non-religious people in the world in 2010, and that number is expected to increase to over 1.2 billion by the year 2020.
Will this tidal wave of secularization continue to wash over planet earth?
I so hope this is true...though I am not seeing it in my little corner of the world. What I am seeing is this: I went to a grandmother's funeral earlier this year. She was 90. When she was 15, she entered into this cultish religion that I was a part of for 30 years. At her funeral, she had 4 sons, their wives, many grandchildren/their spouses and great grandchildren (40+ decendants). 99% of them were in this religion....All because of ONE lady....
I think figures will always be skewed for a number of reasons, the two chief ones being that in many oppressively religious societies, such as much of the MIddle East, people claim to follow the approved religion because admitting one is an atheist can lead to serious trouble, whereas in many liberal societies such as Western Europe, people simply tick whichever religion their family traditionally followed, even though they've never actually practiced that religion, simply because having a religion or not really isn't that big a deal to them. For example, I know many people who automatically tick "Christian" on the census form - but they've never been to a church service other than, perhaps, a wedding or other similar occasion, never pray, do not observe the sabbath, have never even opened a Bible never mind read it and, if questioned, will admit they don't really believe in God. Then there are Buddhists, who may tick "Buddhist" on the census but have no belief in any God, and those who are members of an ethnoreligious group who do not subscribe to that group's religion. For example, I tick the box marked "Jewish" on the census because I do consider myself to be Jewish and will always do so even though I'm an atheist.
So, to sum up, I think it's possible that there are a very great deal more non-religious people than surveys can tell us.
