Facebook denies that friend suggestions are based on location
Facebook said, "We're not using location data, such as device location and location information you add to your profile, to suggest people you may know. We may show you people based on mutual friends, work and education information, networks you are part of, contacts you've imported and other factors."
A spokesperson for the social network had previously acknowledged that location was just one of the factors used to suggest friends, but later said that the company had dug into the matter and found that location wasn’t used. This investigation led to the updated statement above.
