Everybody Lies

Official stats show no changes in child abuse during the Great Financial Crisis. But Google searches for "Why does my dad hit me" (and other similar searches) spiked during that period! In Everybody Lies: Big Data, New Data, and What the Internet Can Tell Us About Who We Really Are, the reader is shown new means of collecting and slicing data that can shed a light on things we thought we knew, but don't.

It's a lot like Freakonomics. It goes deep into some unique data to offer insights that either weren't available before or weren't thought of. I highly recommend the book.
