Facebook's Data Science team recently produced an interesting analysis of what it's calling "coordinated migration" patterns among large groups of people who tend to flock from one city to a common destination (think Warsaw to Chicago, Havana to Miami, or from just about anywhere in Turkey to Istanbul).Kind of interesting. There is probably a lot more data to be dug out of this as far as urban planning, public health and so on go but what hit me is that this is exactly the kind of thing the NSA wants to do with the data it has been collecting only on a different selection set (terrorists). I would love to see what they have generated.
