The Spider-to-Human Ratio

spider to human ratio

Since I like spiders, I was pleased to read a rough estimate of 21 quadrillion for the world’s population of spiders (source: here).

The website http://www.worldometers.info/world-population/ gives the current human population as ~7.4 billion. Dividing the estimated spider population by the estimated human population yields Earth’s estimated spider-to-human ratio: 2.8 million.

Yes, your share approaches three million spiders. At least they are good at taking care of themselves!

  1. I like them too but I’d rather the Wolf Spider’s stay outside. I catch a lot of them and put them in the garage during the winter and outside during the summer. I know it’s not off for them to always be outside but I can’t have them in the house. Sigh. A dilemma, for sure.
