The selfie -- that simple tool of self-promotion -- has moved far beyond social media phenomenon, as researchers with the Selfiecity project can attest. They examined selfles posted in Moscow, New York, Sao Paulo, Bangkok and Berlin and came up with some interesting discoveries.
79 million: The number of selflies posted to Instagram
4: The percentage of all photos on Instagram that are selflies. The rest? Feet, food, friends, shoes, cats, dogs...
50: How much higher, in percentage, of head-tilts in women than in men.
23.7: Estimated median age of selfie posters.
40: The age when men are more likely than women to post selfies.
