Remember the days when college-age cool kids dominated Facebook? As Facebook evolved, its audience changed too. Take a look at the most recent demographic stats compiled by iStrategyLabs after reviewing Facebook’s ad data.

Between January 4, 2009 and July 7, 2009 users between the ages of:

• 25-34 has grown by 60% from 11.2 million users to 18.1 million users

• 35-54 has grown by 190.2% from 6.9 million to 20.2 million users

• 55+ has grown over 500% from 954,000 to 5.8 million users

While the 18-24 year-olds still have a solid presence on Facebook at 18 million users, they have only grown by 4.8%, which indicates a much slower growth rate as compared to older demographics. In addition, the number of people who identify themselves as high school and college students has declined by -16.5% and -21.7%.
