With Twitter that’s not the case. Percentagewise, 25- to 34-year-olds are more into the service than teens, and in 2014, they’ll also represent nearly double the number of users—10.4 million in 2014, compared with just 5.5 million. Furthermore, by 2018, the percentage of 35- to 44-year-olds who use Twitter will nearly match the percentage of teens who do—29.1% for the older group, compared with 29.7% of teens. On Facebook, the percentage of teens using the site monthly currently outpaces the 35-to-44 group by nearly 15 percentage points, and eMarketer expects that gap to remain steady over the next four years.
