Anyone have any statistics on the % of the human population that have 'religious beliefs' and the % of the human population claim to be atheist ?

Here's something from Wikipedia:-
Since conceptions of atheism vary, determining how many atheists exist in the world today is difficult.[23] According to one estimate, atheists make up about 2.3% of the world's population, while a further 11.9% are nonreligious.[24] According to another, rates of self-reported atheism are among the highest in Western nations, again to varying degrees: United States (4%), Italy (7%), Spain (11%), Great Britain (17%), Germany (20%), and France (32%).[25] According to a 2012 report by the Pew Research Center, people describing themselves as "atheist" were 2% of the total population in the US, and within the religiously unaffiliated (or "no religion") demographic, atheists made up 12%.[26] According to a 2012 global poll conducted by WIN/GIA, 13% of the participants say they are atheists.
