America's earliest risers live in Arizona. The country's biggest snoozers live in Michigan. Hawaiians are in bed before anyone else. And New Yorkers really are the last ones standing at the party (or awake, at home, watching Netflix).
That's according to Jawbone, the maker of the popular fitness tracker by the same name, which crunched data on over one million sleep patterns across every county in the country to estimate the average bedtime and wake time for Americans all over the United States.
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.
On a county level, some places have more to brag about than others (if bragging about late bedtimes is something people want to do).
Brooklyn would certainly qualify as one of those places. No county, after all, has a later bedtime than Brooklyn — people living in Kings, New York go to bed at about 12:07 a.m., on average, according to Jawbone.
Brooklyn, as it happens, is the only city that goes to sleep after midnight. Even in Manhattan, where the second latest to bed in the United States live, people go to sleep before the clock strikes twelve (at approximately 11:55 p.m.). In Miami, the city with the third latest bedtime, people go to sleep at 11:54 p.m. on average. In Atlantic City, the fourth, people go to sleep a little after 11:50 p.m. In Los Angeles, the 384th, it's roughly 11:30 p.m.
On the other end of the spectrum are two counties in Hawaii — Maui and Kauai — where people go to sleep, on average, around 10:30 p.m., the earliest in the country.
The latest to bed aren't, naturally, the earliest to rise. Graham and Greenlee, Ariz., as well as Catron, New Mexico, share those honors. The three counties are up just after 6 a.m., on average, according to Jawbone.
Brooklynites, meanwhile, wake up later than just about anyone else. Only seven counties in the United States — Nueces, Tex.; Parke, Ind.; Montmorency, Mich.; Oscoda, Mich.; Pocahontas, W.Va.; Gladwin, Mich., and Charlevoix, Mich.— wake up later than Kings, New York, where people are awake just after 7:30 a.m. on average.
All in all, not a single county's residents were found to average more than eight hours of sleep a night. Some came close — Pocahontas, W.Va., for instance, averages 7.7 hours per night. Sawyer, Wis.; Howard, Pike, and Sevier, Ark; as well as Gulf, Fl., and Del Norte and Alpine, Calif., all average roughly seven and a half hours of sleep per night, according to Jawbone.
Others, meanwhile, are miles—ok, more like an hour and a half—away.
Dimmit and Zavala, Tex., both of which were found to average fewer than six and half hours of sleep per night, are the country's two most sleepless counties. In New York, where people stay up all night(ish), people also don't get much sleep—only about 6.8 hours on average in Brooklyn, Manhattan, and Queens.
