Frekonomics (by Steven D. Levitt and Stephen J. Dubner)

I read this on an airplane, and it actually wasn't a great airplane read in that it went really, really, really fast. (Luckily I had another book or two waiting in the wings.) It was entertaining, though! I'd heard about the whole abortion and crime rate connection back when the book first came out, but I enjoyed reading the whole thing. I kind of wanted a little more detail and depth, but for what it was, it was entertaining. Shrug.
