Over at Internet Monk, Michael Bell has run the latest Pew data through his Batcomputer, and it spit out a very cool graph, showing where people switch when they switch.

Money quote from Michael’s analysis:

Evangelicals are at best currently treading water. Their inflows have
been matched by outflows, albeit coming from different sources. Much to
my surprise, Evangelicals and Mainline Protestants have in fact been
swapping members, I had expected much more of a move from Mainline
Protestants to Evangelicals. This has not been the case as 2.6% of
Americans have moved from Evangelical to Mainline and 2.5% have moved
back the other way. More on this later in the post.
