Hi
Perrine!!!
Yes, Naming trends change very very slowly.
Indeed I dislike the most of the Top30 and the names I would consider are so popular that I dislike them too. I personally know at least three people with each of these names. It is so annoying.
Actually this was the reason why I became a name nerd and I looked for sites like BtN. I used to collect any name that was different from the..."only 100" names that everyone had around me when I was a child! Lol
Names that were fashion in 1990s like
Nicole are still overly popular. Nothing changes.
I think that a reason is the TFR of 1.27. If the most of women are childless and a half has just one child so it is reasonable that they choose names that are ok for all in the couple (she, him, her parents, his parents, friends ect..).
Yes,
Mia means "mine" and I'm a bit horrified that it is so popular. It was a Celebrity name and also as you said a name used by
German speaking community here. But the meaning doesn't change. I would not use it, surely.
