Louisiana is 15.9% French (or French Canadian) ancestry, 4.8% Italian ancestry.
Mississippi is 2.7% French ancestry, 1.9% Italian ancestry.
Orleans Parish, LA is 6.8% French ancestry, 4.2% Italian ancestry.
Jefferson Parish, LA is 18.4% French ancestry, 10.8% Italian ancestry.
This is of course declared ancestry. Many of those putting down their ethnicity as American in NOLA are quite likely to be of French heritage. Especially in Jefferson.
I've always wished the census would get rid of the American ethnicity.
