"OK, but what about us non-religious? Are we growing?"

apparently, you are growing ---
non-religious in 1990: 13,116,000
non-religious in 2001: 27,539,000
I wonder how they came up with those figures. I'm not all that surprised at the growth, I guess.
I only know a few of that 27,539,000, though.
I went and looked at that chart. Interestingly enough, the non-religious are the second largest group in the US, after Christians. I did not know that. Their projections into 2004 make the non-religious 13.8% of the US population.
That's a significant minority, I'd say.
