Facts of the day

In a the-world-in-2014 discussion several days ago, David Miliband mentioned that "one refugee occurred every four seconds in 2014" and that half of all people living on less than $1.25 a day "are in conflict or fragile states." (Btw, what's the definition of a fragile state? Is there a generally accepted one? Possibly, but I'm not going to look it up right now.)
