When the world sleeps

Posted to Statistical Visualization  |  Tags: ,  |  Nathan Yau

An additional hour of sleep can make a huge difference in how you feel the next day (especially when you have kids). It’s the ability to concentrate for long periods of time versus the ability to stare at a clock until your next break. I got the Jawbone UP24 band to try to improve on that, and I still wear it every night to better understand my sleep habits.

So, it only seems natural for Jawbone to look closer at how people sleep as a whole in a couple of interactive graphics. Select your city to see how people sleep in your neck of the woods.

Every now and then we see a set of graphics that shows America’s sleep habits, based on data from the American Time Use Survey. The Jawbone data is likely more accurate though, which makes it more interesting. The former depends on survey participants’ memories and doesn’t factor out things like reading in bed. The latter is actual sleep.
