Many of us don’t think twice when we check-in to our favorite location-based service — but how much of ourselves are we really giving away? While it’s not totally necessary to tell our friends we hit up the local pub for lunch or that we are currently tweeting from the Big Apple, there are a lot of us who do it anyway.

This infographic by Visible outlines the average demographic of geotagging and location-based services and how many of us really use them. Out of the 65 percent of U.S. adults who use social media daily, 14 percent have added the option on Twitter and Facebook that automatically posts their location. Men are more willing to share their location than women — 19 percent of men set up their social media accounts to automatically include location in their posts while just 10 percent of women did the same.

Surprisingly, middle-aged users are the most likely to set their social media accounts to automatically share their location — 16 percent of 50 to 65-year-olds use this option while only 13 percent of 18 to 29-year-olds automatically share their location.

The data also displayed that adults who own smartphones are more likely than any other group to use location-based check-in services like Foursquare or Gowalla - 12 percent of smartphone users have used a check-in service and 14 percent of smartphone owners use automatic location tags in their posts.
