There are, just maybe not exactly in New Orleans itself.
It depends what you call the projects, but there are white people (especially in the suburbs) that live in areas that are known to be the projects, but they just usually aren't quite as expansive and famous as the huge projects in New Orleans.
And I think if I remember correctly, it was a bit before my time, but I thought that there were some white people that lived in a certain project in New Orleans, I think when it was a bit newer. Maybe the St. Thomas? I think I remember someone telling me that.
I think mostly the reason is a lot of the really really poor white people have moved to really really poor areas of the suburbs, instead of directly in New Orleans.
