If there are 6.77 billion people on earth, I would imagine they don't all live in individual homes... 650million homes with broadband, at roughly 4 people per home would be about 2.6 billion people.. no?
I don't know what the rough number of people per household is, but maybe I'm reading this wrong? Did they already take that into account? Meaning, if you had one subscription to a house, but 4 people live there, are they counting that as 1, or as 4?
