My best guess for why Iran is #1 is that in 1990 they were just coming off the disastrous Iran-Iraq war, so the improvement is mostly a rebound from those depths.

They actually started from a mid-range rank of 95th, and improved to 60th.

95/142 is pretty bad for Iran. If you went back further, to 1975, I'm sure they would have been it a lot better shape.

This was a challenging bit of remembering.. trying to figure out not just which countries are doing well but which were in bad shape in 18 years ago versus where they are today. I got everything except for Mauritius and Rwanda. If I'd remembered the Rwandan Civil War started in 1990 I probably would have picked that one up, too.

Many of these counties are majority-Muslim, glad to see good development among them :)

The borders were the same though, easy job for statisticians.

That may be, but I didn't try any of the countries that have emerged from Yugoslavia, because the country was still whole in 1990.

A caveat indicating that would have helped.

Right, but Croatia wasn't a country in 1990. Yugoslavia was the country. Could use a note at the top.

Took me a few tries, but very interesting! Especially good to see Rwanda and Croatia on there after the conflicts they went through... onwards and upwards! :) ;)
