From the Shaping The Newspaper Blog, sourced from a Morgan Stanley Research report:
“To the surprise of many, Facebook in not just the privilege of tech-savvy kids – the college and post-college folks (18- to 24-yearolds), which the site originally aimed to target, now only account for less than 25 percent of total users. The fastest-growing demographic group is women age of 55 and older, up 175 percent since September 2008.”
