A bit of good news for whoever is replacing Atoosa Rubenstein at Hearst's Seventeen: Readers are rich! With an average income of $60,975, Seventeen's little girls live in households where dad is more often a doctor and mom is more likely to have been smart enough not to invest in Enron, as compared to rivals like Teen Vogue and CosmoGIRL, which the 'Toos once edited. Now it's time to cue the rebuttals, with Seventeen's competitors saying household income isn't as important as how much time readers spend with the magazine. Boo hoo — we'll tell you when advertisers stop caring about dollar signs.

But the more interesting bit of info coming out of Mediamark Research Inc.’s annual TeenMark study is the average age of readers:

Readers of Hearst Magazines’ Seventeen also were slightly older than the two other top teen magazines by circulation, with a median age of 16.3 vs. 16 for Condé Nast’s Teen Vogue and 16.1 for Hearst’s CosmoGirl.

That is, Seventeen's readers are actually almost .. 17, not 12 and 13 we imagined. Hell, Seventeen's readers could very well be 19, if it weren't for the two-year-old readers who use the magazine as food and waste clean up who keep skewing the median.
