I'm an avid follower & I love you guys! However, I think it's important to note the background information of your child poverty rate chart. The chart's data is from a UNICEF article ("Tens of millions of children living in poverty in the world’s richest countries") which states that the data reflects only the world's "advanced industrial economies." Third world countries were not included in this study. Some people might get the wrong idea if this isn't clarified.
A very good point and distinction. I thought that was in the fine print after I read the article but was wrong. So, for those who did not click through to the article, it is indeed describing the “developed world.”
