Researchers released a selfie-mapping project called "SelfieCity" to analyze selfies taken in a number of cities.
The project, which was created by a group of independent researchers, searched and extracted data from 3,200 selfies taken in cities including Sao Paolo, Bangkok, Moscow, Berlin, and New York. After extracting, they analyzed the shots then map it along demographic and geographic lines. From there, they found out which city people do smile the most and even know something about the country's culture, the Washington Post reported.
Selfie is a form of self-portrait picture usually taken with the use of hand-held digital camera or phone cameras. It is often posted in social networking sites.
To do the study, 20,000 photos from each of the five cities were extracted, analyzed and trimmed down to 600 through the use of computer software and mechanical Turk.
Though the trimmed number may seem like a lot, there's no indication if it was statistically significant.
The whole process was also lacking especially when it comes to determining age, gender and mood - as those qualities differ from one culture to another.
However, taking away those flaws, the researchers were able to find interesting things on the selfies. One of those is a confirmation for a phenomenon ordinary people and sociologists have observed and noted already - women take selfies way frequently than men.
The researchers noted that 65.4 percent of the photos from Sao Paolo, 55.2 percent of photos in Bangkok, 59.4 percent of photos in Berlin, 61.6 photos from New York, and 82 percent of photos from Moscow, were all from women.
The mood analysis, on the other hand, showed that people from Sao Paolo and Bangkok smile the most. People from Moscow, however, smile the least.
They also studied head tilts angles and discovered that women taking selfies in Sao Paolo, tilt their heads the most -- in an average angle of 16.9 degrees. Men from Moscow, on the other hand, tilt their head the least - in an average angle of 7.1 degrees only.
