First, there's Facebook. Yes, it's still absolutely the most prominent social network, dwarfing every other. 86% of its users come from outside the U.S., and 73% of people earning over $75,000 annually have a Facebook account (while only 17% have a Twitter account). And, our parents are joining in droves: The 45-54 age bracket has grown 45% since the end of 2012.
Twitter users are demonstrably young: 27% of the 18-29 age group in the U.S. tweet, but only 16% of people in their 30s and 40s use the platform. The notoriously youthful Tumblr, meanwhile, is "strong with teens and young adults interested in self-expression," but is the social media outlet with the lowest presence on the income-specific bar graph, with only 8% of U.S. Internet users with incomes above $75,000 using the platform (and an even lower percentage in the lower income brackets). We would hazard a guess and say most of Tumblr's users aren't holding full-time jobs.
Things get interesting when you factor gender into the mix. The stereotypes about Pinterest being a bride-to-be's platform are annoying, though not farfetched: 84% of its users are women (many of whom are tablet users — good for all those aspirational photos!). Following suit is the female-leaning Instagram, with 68% of its users being women. It's pretty clear that women prefer the visually-appetizing platforms, though we wish we could see an official Tumblr gender demographic chart to confirm this. Meanwhile, men still dominate the business-oriented sectors: They comprise 70% of Google+ users, and maintain a strong, global LinkedIn presence. [Business Insider]
