Sorry if I am stealing RRW's thunder, but I thought it would be interesting to see for North America, with a more homogeneous language, based on Province, Territory, and State names and their capitals. I didn't do Mexico as I am unsure about proper pronunciations.
Names:
I used common names, not official ones (i.e. no "Commonwealth of Massachusetts" or "State of Rhode Island and Providence Plantations" just "Massachusetts" and "Rhode Island").
Newfoundland was tough, since "Newfoundland and Labrador" is quite commonly used, but I went with the former.
Florida, I pronounce with 2 syllables, so I went with that, but know plenty of people that pronounce the "i" making it three.
Capital cities:
Same rules.
Quebec City's name is officially Quebec and commonly used as such, teh city is just added as differentiation.
Fredericton I usually hear with 3, but occasionally people pronounce the "er"
Montgomery is much the same, but I rarely hear about the city, so not knowing which was most common I went with what I use.
The capital city names do tend to be noticeably shorter than the State/Province/Territory names
