Can you answer these questions on the state of the world?

The late Hans Rosling found fame through his TED talks on visualising facts about the world. His last book,“Factfulness”, was published a few years ago, and is a great read.

The thrust of the book is that we lazily make assumptions about the world, which are not based on facts. We then formulate big world views based on false assumptions. To make his point, he starts his book with 13 questions on the state of the world. I was surprised by many of the answers. Here are the questions (and the answers). See if you get them right!
