Jawbone … put together a map of when people go to sleep. And there you see mostly people who live in large cities and college towns staying up later. That shows that people in Brooklyn, NY tend to have the latest bed time in the United States (they turn down, on average, at 12:07 a.m.) where as people living in Maui, Hawaii get to bed the earliest at 10:31 p.m.
While Brooklynites do stay up late for the United States, separate Jawbone datashows they pale in comparison to urbanites in other major cities. In Moscow, the average Jawbone wearer goes to bed at 12:46 a.m.
Roberto A. Ferdman adds some important context:
To be clear, the people Jawbone analyzed are those who own and use a Jawbone device, meaning that they are likely of a higher socio-economic background, and, imaginably, inclined to exercise or at least monitor their health.
There’s also the likelihood that not all counties are represented equally. While Jawbone hasn’t divulged how many people were observed in each county, it’s pretty reasonable to assume that far more were tracked in New York City than rural Montana.
Countrywide, some of the trends Jawbone unearthed merely confirm what we already suspected. People who live on the West Coast, for instance, are pretty good about getting to bed early, and people who live on the East Coast, generally speaking, are not. Cities also tend to go to sleep later than rural counties—again, no surprise here.
Over at Jawbone’s blog, Tyler Nolan Jawbone notes that “it’s also clear how our sleep can be shaped by daylight”:
On the western extremes of time zones, people tend to go to bed later, and on the eastern edges they go to bed earlier (for example, look at the Central Time Zone). The starkest difference can be seen on the Kentucky/Tennessee borders between Eastern Time and Central Time …
