Ave # of Facebook Friends
Pew reports the average number of Facebook friends to be 229 (May 2012) which lines up with analysis on the Facebook S1 which pegs it at 234. This huge rise from the numbers Facebook’s shared previously: 130 (2010) and 100 (2008).
However the greater story is in how the numbers vary by generation. With Millennials averaging 318 and in my experience showing significant outliers among college students above 1,000.
