Bill Gates in his blog:
I talk about the developed and developing world all the time, but I shouldn’t.
My late friend Hans Rosling called the labels “outdated” and “meaningless.” Any categorization that lumps together China and the Democratic Republic of Congo is too broad to be useful. But I’ve continued to use “developed” and “developing” in public (and on this blog) because there wasn’t a more accurate, easily understandable alternative—until now.
I recently read Hans’ new book Factfulness: Ten Reasons We're Wrong About the World—and Why Things Are Better Than You Think. In it, he offers a new framework for how to think about the world. Hans proposes four income groups (with the largest number of people living on level 2):
This was a breakthrough to me. The framework Hans enunciates is one that took me decades of working in global development to create for myself, and I could have never expressed it in such a clear way. I’m going to try to use this model moving forward.
Why does it matter? It’s hard to pick up on progress if you divide the world into rich countries and poor countries. When those are the only two options, you’re more likely to think anyone who doesn’t have a certain quality of life is “poor.”
