Cat people are single, dog people are popular (according to Facebook)

Data scientists at Facebook have sampled 160,000 users and confirmed some long-held stereotypes about cat people versus dog people

Montagues and Capulets. Edison and Tesla. Bloods and Crips. Among history's greatest rivalries none has been so fierce as that between cat people and dog people.

In honor of International Cat Day, Facebook researchers examined the behavior of these warring factions to find some insight into who they are and how they operate. The team of data scientists wanted to find out who has more friends, who is more likely to be single and who has the best taste in TV.
