For most social networks, the 25-34 age group has control, but not by much. Facebook, Google+, Twitter, Instagram, and Pinterest fall into this category. Millennials age 18-24 consist of the most users on SmapChat, Vine, and Tumblr. LinkedIn is the odd-one out, with 35-44 year olds leading the way.
What marketers should take away from this chart is the content they push out on each social network should relate to its key demographic. Posting the same copy and link on twitter does not mean it will perform the same on Facebook or LinkedIn. Businesses should also be inspired by this chart to think outside the box and create content that different age groups will enjoy. There are ways for even the most boring companies to produce engaging content. Yes, even on Vine and SnapChat too!
This also might show marketers that the 65+ crowd is not too strong on social. Rather than spend the time and money to reach 65+ individuals, perhaps other marketing efforts, such as direct mail or email newsletters, are the best option. At the very least, this chart should make marketers think twice about the content they are producing, the channels they are using, and the types of users each social network has.
