And if you have difficulties how to call people from countries like
Kiribati
Liechtenstein
Saint Kitts and Nevis
Saint Pierre and Miquelon
Cote d'Ivoire

there is always The World Factbook

(Boy, was I disappointed when I hoped to find out finally how the people from the Holy See are called (Holy Seers?) and the factbook did not give a noun; well, even the CIA doesn't know everything; and did I detect a tiny bias when the noun for people from Gaza strip (I didn't seriously expect to find Gaza strippers) was 'not available' instead of simply 'Palestinian'?)
