Today's chart tells that story in the simplest terms possible. As Visual Capitalist's Jeff Desjardins notes, by showing the changing share of the global economy for each country from 1 AD until now, it compares economic productivity over a mind-boggling time period.
Originally published in a research letter by Michael Cembalest of JP Morgan, we've updated it based on the most recent data and projections from the IMF. If you like, you can still find the original chart (which goes to 2008) at The Atlantic. It's also worth noting that the original source for all the data up until 2008 is from the late Angus Maddison, a famous economic historian that published estimates on population, GDP, and other figures going back to Roman times.
