71% of adult internet users/58% of entire adult population
Fully 71% of online adults use Facebook, a proportion unchanged from August 2013. Usage among seniors continues to increase. Some 56% of internet users ages 65 and older now use Facebook, up from 45% who did so in late 2013 and 35% who did so in late 2012. Women are also particularly likely to use Facebook compared with men, a trend that continues from prior years.
