Thank you, Ms. Barrows, for setting me on the right path.
Haven’t a clue how to interpret this chart to reach the conclusion of The Economist. Can someone explain this?
Daily chart: wine consumption by country. America glugged more still and sparkling wine than any other country last year. Together with the Chinese and Russians, Americans are driving growth in global wine consumption, which has increased by 3.5% since 2007.
I had to stare at it in puzzlement for the longest time before realizing why it works out; it’s per person, so once you multiply by the actual populations of the countries shown, it’s a significantly different ordering as to which lines will be longest. So the customers in the US and China aren’t drinking much per person - but there’s an awful lot of them drinking.
