West Virginia gets the worst sleep in the US. Oregon gets the best.

Many Americans don’t get the roughly 8 hours of sleep recommended by experts. But who’s sleeping the worst? This map has some answers:

The data is the most recent that’s available on the topic from the CDC, from 2008. It’s from a poll that asked people how many nights out of the past 30 they felt that they’d had insufficient rest or sleep.

The worst-off are West Virginia and Kentucky, each with more of one-third of respondents telling pollsters that they had insufficient sleep over at least 14 of the previous 30 days. These states are geographically located in what seems to be a region of sleeplessness, with many surrounding states sleeping badly, as well.

Things get better in the Midwest and West. Oregon seems to be winning at sleeping, with only 23 percent of residents saying they got insufficient sleep. Wait. Did I say that’s winning at sleeping? That’s still almost a quarter of Oregon sleeping poorly.
