A Middle-Class World

I thought that the chart looked strangely linear, so I entered the numbers in Excel and plotted an XY chart rather than a bar chart.

It is highly non-linear. A power regression fits the data the best. (y=1E-108*x^32.57, R^2=.9809)

Interestingly enough, you can get an almost perfect fit if you only plot the years 1820, 1913, 1950, and 2005. (R^2=.9985, y=5E-114*x^34.25)

1980 is a huge outlier. That's the damage socialism caused, especially Maoism and Indian style socialism.

I thought the middle class was shrinking ;)

MISPRINT

"...54 percent in 2005 to a projected 79 percent in 2005."
But a fascinating snippet - thanks.

Dear AK, please could you give some indication of the oprational definition of Middle Class used in this book?

Do a exponential regression on the data for 1820, 1913, and 1950. Extrapolate to 2025.

Had socialism never occured, 96.7% of the world's population would be middle class in 2025 vs. the 79% now projected (I get 76.5%).

66% of the pop would be middle class in 2005, instead of the 54% we now have.

Socialism/ Maoism did that much damage. And it isn't like 1950 was a good year or anything. It was only 5 years after WWII, after all. Imagine where the world would be if, say, WWI had never happened and the positive trends of the 19th century had continued.

A couple of typos: "23 percent in 1850" should be changed to the much-less-shocking "1950"; and as pointed out above, "79 percent in 2005" should be "2025".
