Gross World Product, according to Wikipedia is

the combined gross national product of all the countries in the world. Because imports and exports balance exactly when considering the whole world, this also equals the total global gross domestic product (GDP).

I got curious about the world-wide GDP after thinking about two previous posts:

What would happen if you multiplied the drastic increase in population with the radical increase in per capita income? I made a feeble effort to multiple the two data sets and quickly realized that wouldn’t work. Poked around a bit on the ol’ internet thingie and found the answer at Wikipedia – *gross world product* is what I was looking for.

**27,000 year time horizon** – Check out the graph at top of this post for the estimated *gross world product* on a very long time horizon, specifically from estimates back in 25,000 B.C. through 2014 A.D.

With that 27,000 year time horizon, there is a radical turn in the 1900s, at which point the graph appears to goes from horizontal to straight up vertical.

That is too long of a time horizon to understand, so I broke it out into smaller blocks.

**Last 2,000 years – **To remove the many earlier millenniums of slow growth, time horizon was revised to 1 AD through now. Notice there is still a radical change in the 1900s. With the dramatic changes in the last 200 years, the line from earlier looks like it is flat, but it isn’t.
