It's not clear from the Wikipedia list if the language categories are mutually exclusive. For example, it seems quite likely that nearly everyone who speaks the Wu, Jin, and Min Nian Chinese family languages also speaks Mandarin.
I'm not even sure what it means to say that Min Nian is the native language for anyone in Taiwan. Sure, lots of people learn it at home but anyone under 60 is going to be just as fluent in Mandarin.
