How Do You Call A Person From Niger?

HAHAHA!!!
I was born and used to live in France and
that was always an issue. I hated when people
called me "Nigèriene", mais je vien pa de Niger moi!!
I used to get really angry.
In English, there really isn't a difference, I mean
a person from Nigeria is NigeriAN and a person from
Niger is NigeriEN. Same thing in French. Except that in
French it's a matter of pronounciation and the accent on the "e".
NigériANE versus NigèriENE,
