I've even heard
Liam used in Brazil, where I'm from.
The only parts of
Europe where I could imagine it isn't popular are the former Soviet countries (specifically the ones that use Cyrillic) and Muslim-majority areas like Bosnia, Albania, and Kosovo.
I agree that it seems like most American Liams are fictional (or little kids). The only real American
Liam I know of who isn't a child is
Liam O'Brien (a voice actor - he was born in 1976), but he isn't famous outside of anime and video game fan communities. TV is notorious for predating naming trends - it's not unusual for an American TV show to give adult characters names that didn't even chart at all until 10 years ago.
When do you think
Liam is going to start falling in the US?
