Does ARIS data show an atheist revival?

Pastordan at the Street Prophets blog says "I sincerely doubt" the absolute number of atheists counted by the latest American Religious Identification Survey (ARIS) is soaring.

We will find out when it is released on March 8. Meanwhile, although free-thinker-inclined Epiphenon uses some data that leaked out to make a different case, pastordan says:

What seems more likely is that "weak" Christians - those who are not affiliated very tightly if at all - feel more comfortable identifying as such. That's the number that's doubled since '91.

It is interesting that the rate of growth in self-disaffiliations, skeptcisim or whatever mixture of sentiments it is, has slowed. Yet the percent who self-identify as atheists or agnostics has grown dramatically.

All of which typically has no simple, synoptic demographic meaning. The data, like the human behavior it attempts to measure, is always complex, messy. But since '91 it hasn't indicated a revival, of any kind.

More like a slow falling away and acceptance of the attendant labels.
