2,000 Years of Economic History in One Chart

Michael Cembalest, head of investment strategy at JP Morgan, is famous for his beautiful, insightful charts. His latest (courtesy of Paul Kedrosky) illustrates two millennia of world economic history:

According to the chart, India (orange) and China (red) together comprised more than two-thirds of the globe’s economic activity back in year 1 (well, not so much the globe, but the chosen countries). By 1950, their share had fallen to only one-eighth, thanks to the growth of the United States (green), Western Europe (shades of blue), Russia (gray), and Japan (yellow). Since then, China has been gaining share.

Not surprisingly, the chart has already attracted attention in the blogosphere. Over at the Atlantic, Derek Thompson slices and dices the data to see how much of the pattern reflects  the ebbs and flows of population vs. productivity.

At the Economist, meanwhile, K.N.C. channels Edward Tufte, expressing appropriate alarm about the compressed x-axis. The first millennium gets as much real estate as the 1990s. K.N.C. then offers another approach:

Given data limitations, this chart also compresses the x-axis, but using bars and variable-width gaps make it much clearer that there are jumps between years. The focus on a limited number of countries also makes it clear that the chart omits countries that account for 30-40% of world GDP. In Cembalest’s chart, in contrast, one wonders what happened to South America, the Nordic countries, Canada, Africa ex Egypt, etc. His listed countries appear to sum to 100% of world GDP, but large swathes of the world are unaccounted for.
