A tweet popped up in my feed recently that posed a really good question. On first blush I thought "Oh, I can answer this!" then upon further reflection I realized I can't.
In the case of "New Yorkers", we add "-er" to "New York". In the case of "Scandinavian", we add an "-n" to "Scandinavia". And so on.
So, to finally propose the question that was asked on Twitter:
What is the proper demonym for someone from Shreveport?
I assume it's "Shreveporter" but that doesn't quite sound right.
I saw this general discussion, but it doesn't answer this particular question.
