Global maize (corn) production

Here’s something different from what I normally do. I found myself wondering recently about the amount of corn grown in the world. I found out here that in 2014-15, an estimated 175.5 million hectares of land is under corn production.

How much is that?

Well, it turns out that 175.5 million hectares is about 677,606 square miles.

This five states shaded in this map total 678,660 square miles, which is pretty close to the amount of land in the world under corn production.

What do you think? Should I post more maps like this?
