This took me a minute too. The opening graph is from the Office for National Statistics. The ONS is a UK govt department. So there is some UK data in the article but this is first-year mortality, not first month. The author does say: > The precise birth data needed to produce these comparable rates is not available for all countries, so only a selection of OECD countries is shown. Perhaps this is the reason. I do agree though, it's mighty strange to have not included an interpretation of you're going to mention them in the text. Perhaps they were excluded after the text was written?
