The ratio between photos of peoples by themselves and photos of people with other people is about 1:1. Suprisingly, the ratio doesn’t change no matter if looked at female, male, and it doesn’t even change with age. In all categories, the percentage of people who have only themselves in the profile photo and who have other people with them is always about 50%. The total number of people we have data on is not very large, so it is difficult to get a very reliable data, but the most difference in numbers between photos of people by themselves and photos with other people is 5 in all categories, which means that there isn’t much difference. This is very interesting since profile pictures are for knowing who the user is texting.
