Facebook (and other social networks) has been skewing older for a while, but the trend has been “massive” in the past six months, according to InsideFacebook.com. In the past two months alone the number of new members over 35 has doubled. Marketers take note: the median age is now over 25, and the largest single group 35 to 44.
Women over 55 remain the fastest growing group, and growth among the teen and college-age set has been relatively paltry. In absolute numbers there are now even slightly more members between the ages of 45 and 65 than there are 13-to 17-year-olds.
Looking at Facebook US audience growth over the last 180 days, it’s clear that Facebook is seeing massive increases in adoption amongst users 35-65. The fastest growing demographic on Facebook is still women over 55 — there are now nearly 1.5 million of them active on Facebook each month.
The biggest growth in terms of absolute new users over the last six month came amongst users 35-44. Over 4 million more US women 35-44 and nearly 3 million more US men 35-44 used Facebook in March 2009 compared to September 2008.
