There are tons of factors that can affect your sleep on a nightly basis — like how much activity you got that day, what you ate, and how stressed you are. These factors usually vary based on your habits, but Jawbone, maker of fitness wristbands, was able to gather data that shows how Americans sleep in general.

The chart is based on data from more than one million wearers that use Jawbone’s band and app to track their sleep. It’s not a completely conclusive study at how all Americans sleep, but there are some common trends worth noting.
