Countries With the Highest Rate of Emigration

This data is a little out-of-date now.

Also, not sure that DRC would show up anyway given that it has a pretty massive population. If you notice, pretty much every country on here is pretty tiny and/or sparsely populated with the notable exception of South Africa (in last place). The smaller populations means a mass migration is going to have a higher impact %wise. The biggest countries to crack the top 19 are Syria at 22 million and Somalia at 10 million and both of those countries have had, I daresay, more problems than the 3 you listed put together. You need some pretty severe anarchy and social upheaval to generate the kind of mass exodus that takes a significant chunk out of a population of 10 million + people.
