Inhabitants of Vatican City would be referred to as ____

Keep that blank clean. No religious flaming.

What I mean is this: inhabitants of America are Americans, inhabitants of Ohio are Ohioans, and inhabitants of Cincinnati are Cincinnatians. But what demonym would you use or have you seen used to refer to a resident of Vatican City? This site doesn't have one in its list, and the example for Sioux City, Iowa, found on this Wikipedia page would seem to suggest that maybe it's Vatican Citian, which just sounds awful.

Maybe it's one of those places that has never had a demonym. After all, "demon" does appear in the word…

According to the CIA World Factbook, there is no official demonym for the Vatican City. I think I have seen Citizen of the Holy See used in print, although I can't remember where.

I don't know the answer to this, but there are some sites with fairly comprehensive lists of countries and their demonyms, and they all list VC as 'none'.

Here is one of those sites.

Also, this response seems fairly authoritative.
