• People take fewer selfies than you’d think. According to SelfieCity’s data, only 3% to 5% of the 300,000-plus images that they examined were actually selfies.

• Women take more selfies than men. “In every city we analyzed, there are significantly more women selfies than men taking, from 1.3 times as many in Bangkok to 1.9 times more in Berlin,” Stefaner says. In Moscow, the discrepancy is even more striking: 4.6 times more women take selfies in the Russian capitol then men. No matter where, if a man takes selfies, though, he’s likely to be older: the median age of men who post selfies on Instagram is more than 30 years old.

• Women strike more extreme poses in selfies (especially in São Paulo). According to SelfieCity’s research, women tend to take more expressive, sexy poses than men in their selfies. On average, the head tilt of a woman’s selfie is 150% higher than for men (12.3° vs. 8.2°). Translated, this means an awful lot of women take selfies holding their cameras way above their heads. But in São Paulo, it’s even crazier: there, the average head tilt for females is 16.9°! Guess they want to fit their bikinis in-frame.
