According to the Social Science++ blog, that is a strong indicator of un-democratic-ness: no free elections, military interventions in government, no power sharing, and so forth. So are the words “Arab,” “Islamic,” “People,” and “Socialist.” On the other hand, the words “Principality” and “Commonwealth” usually mean your country is more democratic than most. Both “Kingdoms” and “Republics” are somewhere in the middle.
So, if you live in the Commonwealth of Australia or the Principality of Andorra, give yourself a pat on the back. On the other hand, those of you living in the Democratic Socialist Republic of Sri Lanka or the Great Socialist People’s Libyan Arab Jamahiriya have my sympathies.
