You know you take a lot of photos on your phone, but you've probably never tracked just how many. A new study by Intel and Lineage Labs examines exactly how often we snap pics — and how many of those are selfies. Oh boy.On any given day, nearly half of Americans take at least one photo. Among those of us who consider ourselves regular photo-takers, the average is five photos per day. This equates to at least 1,825 new photos on your phone each year — but for the 17% of us who take the same photo four or more times in an attempt to get the perfect shot, that number could be significantly higher.Surprisingly, only 6% of photos taken in the U.S. are selfies , a statistic that can only be explained by the absurd number of photos I take of my cat each day. According to the study, the phone-photo numbers actually break down thusly: 29% are of friends and family, 20% are vacation- or travel-related, 19% are of kids, and 13% are of pets. But, for the 18-to-24-year-old set, 16% of photos taken are selfies — an average of six photos per day.Those photos don't just sit on our phones (well, not all of them). The study found that 42% of Americans share their photos on Facebook, while 12% do so on Instagram. Considering Facebook's over 1.3 billion global active users (compared to Instagram's 400 million ), that stat makes sense. The 18-to-24 age group shares the most often and the most diversely: 53% of their photos are shared to Facebook, 31% to Instagram, 25% on Snapchat, and 15% on Twitter. Americans' number-one reason for unfollowing someone? Excessive selfies tops the list, followed by too many political, religious, or food photos.How does your selfie habit compare to that of the "average" American?
