Sorry about the missing data for this quiz. I tried to add what I thought would be some of the more common answers grayed out in the quiz. Other countries that I suspect could be in the top 15 that also have no data are Sudan and Tanzania. The nearest misses that I found data for were Iraq at 10 000, the UAE at 9 083, and Russia at 7 500.
