Small island states (island states with populations under a million) do stand to benefit from tourism money spread between few people. None of that is to suggest that such money will necessarily benefit many, or that those states will do much to capture a significant portion of it and use it for health and education - the two other social aspects that are measured along with income in the HDI.
In the case of Mauritius, Seychelles, and Cape Verde they don't share a history with the rest of Africa, being uninhabited until the last few hundred years.
I think part of it is corruption, or other foreign interests controlling operation. Google something like "money laundering mauritius"; I get the impression it's like Nauru was, or I think Ukraine, where foreign entities are looking for a controllable "state" to exploit for global taxes or rebates, or the general movement of money. Keep it functioning at a high enough level for competence, and a low enough level to maintain power over
So basically it's the name the countries that border the Mediterranean, small island countries, Commonwealth countries that haven't had recent civil wars and Gabon. The next two hold to that pattern as well.
The safest place to be in Africa is...not really in Africa. I guess that makes sense - it's a tumultuous country. But even with the flag I was thinking - Really? The SEYCHELLES?!
Why is that? Not many countries in Africa have a smaller population than metropolises such as Lawton Oklahoma or Scranton Pennsylvania. Especially when you see the pattern of the countries on the list.
I didn't even know which flag that was, and I got Seychelles. I guesses all the little island countries first. It makes the most sense, both because it's easier for countries with low populations to prosper, because access to water usually means access to food, and because the natural boundaries spare those countries from so much of the violence and upheaval that plagues the African mainland.
It's more of an indictment of the rest of the continent than anything praise worthy they are doing. The only country in the entirety of the Americas or Europe that is appreciably worse is Haiti. So think of all the problems in El Salvador or Bolivia or Moldova and you'll get a picture of what it's like in one of the better places in Africa.
I'm always surprised how Rwanda doesn't show up on these lists. From what I've just studied online, everything seems to be going rather smoothly over there.
Also, from what I can tell, Rwanda started out from basically the bottom (or close to the bottom) after its internal conflicts and genocide in the '90s. The growth they have had is impressive indeed (they are at about the same HDI as Nigeria now), but because they started out so low, the progress they have made has only gotten them so far.
Amazing that Libya makes the list considering they don't even have a single government with control over the whole country. Also, there are parts of Spain, Portugal and Italy in the African continent. Shouldn't they feature on the list?
High life expectancy, high income, and high standards of education compared to the rest of the continent. Libya is not doing so well right now, but Tripoli losing control over parts of the country isn't going to have an immediate impact on those three things, and when your competition is Niger and Burundi, well...
I don't know if it tells anything about HDI, but from what I've understood, you can quite comfortably shop in stores like M&S and H&M nowadays in Tripoli.
Also what I've heard, the majority of university students in Libya are female. Still not directly about HDI but I think that's sign of a developed country.
To your last comment: maybe. It could also be a sign that they were lagging behind in gender equality and only recently has the gap started narrowing and they're still in a period of catching up. I think that's at least part of the reason why female university enrollment in Saudi Arabia is presently so high. And the fact that there are more women currently studying to be doctors there than men may at first seem to point toward a progressive society until you realize that the reason why demand for female doctors is so high is because of a backward sex-segregated culture that makes it impossible for male doctors to treat female patients, creating a situation where healthcare for women is extremely inadequate.
^anyway my point was be careful when looking at a single data point that paints a very narrow and misleading picture. Same thing happens in the USA when they look at the difference in mean wages between men and women, when American women are some of the most privileged people on the planet.
I've heard about and lived the experience. Women in the US are substantially more privileged and have been since at least the closing decades of the 20th century. Not to imply that American men are less privileged than those in Libya...
Try the northern countries bordering the Mediterranean, the islands in the Indian Ocean, and the oil-producing countries with small populations. Then try southern countries and countries where they are trying to fight corruption. That gets the five northern countries, Seychelles and Mauritius, Gabon, Soputh Africa, and Botswana. That would leave you typing the 'extra' countries of Comoros, Equatorial Guinea, Namibia, and Rwanda, all of which are close in the rankings and would in some years be in the top ten.
