Youth Trends (via eMarketer) just released the results of their most recent quarterly survey about 17-to-25 year-olds Web site usage.

Highlights:

• Facebook is the top site for nearly 70% of females ages 17-25 and 56% of males of the same age group
• It was “the first time that Facebook was tops among both women and men”
• “Two blogs were in the female top 10 list for the first time: Pink Is the New Blog and What Would Tyler Durden Do? (WWTDD). Both blogs have an entertainment/gossip focus, which Mr. Weil (Josh Weil of Youth Trends) says “is consistent with Gen Y females’ current adoration with content surrounding celebrities and their ‘uh oh’ moments.” “

• “MySpace was second on the top 10 list for females, but it remained sixth for males, with the percentage of 17-to-25-year-old males listing it as their favorite moving up slightly from 13% in the previous quarterly listing to 14%. “
• “The average 12- to 17-year-old spent 260 minutes on MySpace and viewed about 808 pages. By contrast, the average 35- to 54-year-old spent 179 minutes on the site and took in 560 pages,” Ad Age reported in October (but did not cite the source of the data). “

This survey is conducted quarterly

What it means: this survey asks respondents to name their three favorite sites (on an unaided basis), which is all about usage but also brand awareness. It tells a lot about the strength of Facebook in that specific demographics. In addition, I think it’s really impressive that two blogs get mentioned by females ages 17-25: Pink is the new blog (#196 in Technorati) and WWTDD (#477 in Technorati). According to this site, WWTDD had 5 million monthly unique visitors and 21 million monthly page views in January. Very good for a “parasitic” medium… (I’ll get back to that news next week…)
