Ha! That depends on what you consider to be a third world country. It's an outdated term by most standards, but it hasn't really been replaced by anything generally accepted and precise. Most people would say that anything that isn't NA or Europe is 3rd world, but not really so. Most would actually be considered 2nd world or semi developed as opposed to third world, which usually means much of africa and the less developed countries in Asia, plus some central America, Cuba and Haiti. Still, to answer your question, most of Europe, about half of South America, probably only Panama in Central America, large parts of southeast Asia. Pretty much anywhere you want to go. We're chauvinistic about out culture, and we like living where we live (mostly) but as a place to monger Montreal is only the best of the worst (North America), Virutally anywhere else is better to monger. That doesn't mean that I'd want to live in all of them. However, if the OP was tying his residential decisions strictly on the basis of mongering he could do far better in a huge variety of other places.
