As one of the underwriters of Twitter’s recent IPO, bank JP Morgan may not be a neutral when it comes to the company’s prospects. That said, it also has plenty of data on Twitter, some of which was shared yesterday. Based on numbers from comScore, it aims to show that Twitter is appealing to teens and early twentysomethings, with a greater proportion of its users falling into those age categories than Facebook, and the internet as a whole. The stats claim that 32.3% of Twitter’s global desktop users are aged 15-24, compared to 28.9% for Facebook. If you just consider mobile users, 24.8% of Twitter’s are aged 18-24 in the US, compared to 19.4% for Facebook – comScore doesn’t survey under-18s for its mobile stats. The aim of releasing this data appears to be showing that Twitter is attracting fresh blood rather than just the slightly-older demographic that fuelled its early growth. What’s not included in the comparison, however, are apps like Snapchat and WhatsApp, which are arguably the more important comparison for Twitter in gauging its appeal to teens.
