The median income of Tumblr users is $80K a year
"New market research provided by Tumblr to AdWeek reveals that the median income of Tumblr users is higher than that of other main social media platforms.
That means that all those businessy types who spent years declaring Tumblr’s business prospects “unattractive,” and handwringing over its perceived cultural status as a vapid, arty playground for teenage girls may now be eating their words. It turns out Tumblr’s younger, mostly female demographic has more money to spend than everyone else.
Tumblr reported to AdWeek that the median household income of its user base is $80,075. That puts it just ahead of Twitter and Facebook ($79,562 and $78,967, respectively), and well-ahead of Pinterest ($70,124).”
