According to the SVB data it appears that in the four major cities - Amsterdam, Rotterdam, the Hague and Utrecht - Mohamed (and its variations - Mohammed and Muhammed) is by far the name most given to boys.Islam in Europe has a full translation of the item here.
In the Hague they're even in places 1, 2 and 5 in the top five. The name was given three times as often in 2008 as the next most popular boy's name: Jayden.
The name is also very popular in Amsterdam. In the capital Mohamed and Mohammed take the 1st and 4th places. Rayan, Adam and Max follow at a great distance.
In Rotterdam Jayden is the name most loved by parents, but if the different spellings are added together, this name is once again number one.
In Utrecht, the fourth city of the Netherlands, Mohammed is also on top, but is followed immeidately by Adam, Lucas, Stijn and Daan.
Is it me, or does the fact that second and third generation immigrants of muslim descent so massively name their children after the founder of their religion/ideology hint at a certain unwillingness to integrate and an in-your-face kind of mind-set?
