The fastest growing demo on Facebook is . . . Grandma! Actually, adults 55+, clearly not all of whom are grandparents. But staying in touch with family members is a primary motivating factor for “older” adults to join Facebook. This demo grew over 900% in 2009. Yep, 900%.

Facebook is now the most visited website among ALL adults, garnering more visits even than Google.

A few more interesting stats. Note that teens only make up 10% of Facebook’s users. The rest are all old enough to vote. 🙂
