How Facebook Collects Data About You to Target Ads (And How You Can Change That)

Facebook knows a lot about you, like where you work, where you live, and your relationship status. But that only covers the personal details you elect to make public online—there’s a whole list of undisclosed information Facebook compiles on each of its users for advertising purposes. If you’re not ready to delete your account for the sake of privacy, you can review and edit your own list of categories for targeted ads in a few quick steps.

A recent episode of the podcast Reply All delved into how Facebook chooses ads based on the preferences and lifestyles of its users. Cat lovers may see ads for cat food pop up beside their news feed, for instance, or someone planning a vacation may be shown ads for hotels. Sometimes, the specificity of these advertisements can feel very creepy. The hyper-targeting has even convinced some users that Facebook is eavesdropping on their private conversations through their devices (which Facebook denies), but the truth is that Facebook has learned enough about the kind of person you are to make really accurate educated guesses about what you want to buy.

So what exactly are the details Facebook looks at when targeting ads? You can find them by going to your “ad preferences” page, clicking on “your information,” and then going to “your categories.” There you’ll find everything from your political leanings and the industry you work in to the devices you own. Facebook doesn't always get these things right, but you may be surprised to learn how much the site knows regarding areas of your life you’ve never posted about in the past. I hardly ever update my profile, but according to my categories page Facebook somehow knows that I live with roommates and that I like to travel. That's because some of this information isn't based on my Facebook activity, but on information Facebook gets from my behavior on other sites.

You can get Facebook to stop using these categories to target ads by clicking the “X” beside the entry. But don’t expect the targeted ads to disappear after purging the page—according to ProPublica, the “your categories” section doesn’t paint a full picture of what Facebook thinks you like (for a more complete version of that list, you can download ProPublica’s Chrome extension).

Want a better way to get rid of targeted ads? Go back to the “your ad preferences page” and click on “ad settings.” From there, you can disable the “ads based on your use of website and apps option.” That way you can online shop without ads for the item you just bought following you back to social media.

The Worst Drivers In America Live in These 15 States

No matter how many times you've been cut off on a road trip, anecdotal evidence alone can't prove that a certain state's drivers are worse than yours. For that, you need statistics. The personal finance company SmartAsset compiled data related to bad driving behaviors to create this list of the 15 states in America with the worst drivers.

This ranking is based on four metrics: the number of fatalities per 100 million miles driven in each state, DUI arrests per 1000 drivers, the percentage of uninsured drivers, and how often residents Google the terms “speeding ticket” or “traffic ticket.”

Mississippi ranks worst overall, with the second-highest number of fatalities and the second lowest percentage of insured drivers. This marked the third year in a row Mississippi claimed the bottom slot in SmartAsset's worst driver's list. This year, it's followed by Nevada in second place and Tennessee in third. You can check out the worst offenders in the country in the list below.

Some motorists may be more interested in avoiding the cities plagued by bad driving than the states. These two categories don't always align: Oregon, which didn't crack the top 10 states with the worst drivers, is home to Portland, the city with the worst drivers according to one quote comparison site. After reading through the list of states, compare it to the cities with the worst drivers in America here.
