This project is studying the way people take self-portraits in different parts of the world – over 120,000 selfies from Berlin, New York, Bangkok, Sao Paolo or Moscow have been analyzed. Are women more likely to take selfies than men? In which proportion? Do people smile, tilt their head, crop the picture? All these questions have been answered and the results are displayed in very well-made interactive data visualization examples. The complexity of the study and the insights found made it a real challenge to expose the results, which they addressed very well, creating one of the best data visualizations of the past years.
