54 million people die each year (150k / day)
Also, according to all statistics, Facebook has actually been GROWING. They have 1.11 billion users now compared to less than 1 billion last year. Something like a 26% growth if I recall.
Come on people, there are only a finite number of internet connected human beings on this planet. Growth HAS to slow down at some point. They're not gonna double their userbase YoY if they already have over 1bn people on their service....that'd literally be impossible.
