Europe, at least Western Europe is in decline, and will be overwhelmed by the Muslim invasion in the coming decades. The creation of the grand caliphate of europistan is well underway unless indigenous Europeans do something about it, but they haven't yet; and each year they become fewer and weaker as the invaders outbreed them.
Plenty of stories of Europeans fleeing Europe, haven't found any country, UN or EU collecting or at least publishing the numbers, but it's happening and will likely accelerate.
As I've said many times: when you're on a sinking ship in the middle of the ocean you have three options: try to save it, sink with it, abandon it. As many first world people are starting to realize the futility of saving it, a minority who have the means to do so are abandoning it; the rest will be trapped and sink with it.
In his essay, "Fate of Empires", Glubb defined common phases of an empire's rise to its' fall; during the decline there are often reactionary movements that attempt to go back to better times; these are short lived and futile as once a society/country/empire gets to a certain point of no return, there is no chance to save it...the collapse is inevitable. This is true of all long gone cultures, societies, empires of the past; to think Western Europe, EU, the USA, etc. are immune to this is the ultimate hubris or denial.
