...And the article disregards all of that by using a high-income-adjusted poverty line for low/medium income countries. Textbook data crime: such a strange hill to die on! The data is all there, in the linked studies. They could easily have used the actually correct data (i.e. per-country poverty lines). But then e.g. China would go from 90-100% poverty bracket (dark red) to the 10-20% bracket (light brown), which is obviously not the conclusion that the blog post* wants readers to be impressed with. * authored by the director of a global development program at Oxford
