GlobalWebIndex: Usage habits of major social media users around the world in Q3 2013

Google+ and Facebook usage in Q3 2013
In the third quarter of 2013, GlobalWebIndex surveyed 42,169 people about which social media/network services they had used in the past month.

During this period, 21.64% of the total number of people surveyed used Google+. This ratio is similar among people aged 16-44, and the ratio of people aged 45-64 is significantly lower, with an average usage ratio of 14.29%. Since there is no relevant data, it seems that no one over 65 years old uses Google+. However, we do not think that there are no Google+ users over 64 years old, or that all Google+ users died before 64 years old.
The author believes that in fact the idea that "Facebook is dead among teenagers" is incorrect. Although the use of Facebook by teenagers is decreasing, the causal relationship is not that simple.
