Actaully the black demographic had a 5% increase. Of course, I wonder how many of those are immigrants as well.
Crap, you're right. Even so the increase in the latino population is proportionally much larger. I wonder how these numbers track against the demographics change in the US as a whole, too. That might well have something to do with it, though I'm pretty confident that the US population didn't change nearly as much as the JWs did, so there's still definitely a lot of churn indicated.
