[qi:109] Forty-eight percent of American 18- to 24-year-olds were on Facebook as of June compared with some 31 percent in the same month last year, based on figures provided by comScore, painting a sharply different picture of young social network users than can be found in the UK. A report out today by the Guardian claims the number of UK citizens age 15-24 with a profile on a social networking site dropped for the first time this year due, it says, to increased adult presence.
According to comScore, the number of unique U.S. visitors age 18-24 on Facebook as of June was 14.3 million vs. 9 million in the same month in 2008. In order to figure out what percentage of that age group was on the site, we divided the comScore numbers by U.S. Census Bureau population figures. While it’s not an apples-to-apples comparison to the study cited in the Guardian — not by any means — the increased presence of young U.S. adults on Facebook is undeniable. But so is that spike in the number of adults. The number of unique U.S. visitors age 35-44 on Facebook in June was more than double than it was a year ago, at 16.3 million vs. 6.8 million.
