Where did you get your numbers from? Before 2012 it was less than a thousand a year. 2012: 1500, 2013: 3000, 2014: 7000.
about #4 you have no idea what you're talking about. Sorry.
(If you ask how do I know, I lived in France for several years and a large part of my family lives there and I still go there a couple times a year)
In the past 20 years it has never been below a thousand a year. That is a fact.
My numbers are from the the official records. 4% is also not a made up number. And the other numbers you posted agree with me.
I'm not sure why living in France or having family there makes you know the official numbers any more then me living in Israel makes me the prime minister
