Excerpt from this article:
Findings from OII indicate that at least 1.4 billion Facebook members will die before the year 2100. In that scenario, based on last year’s user levels, experts believe the dead will surpass the living on the social media platform by 2070.
The report looks at this phenomenon in the extreme, predicting that the number of dead users could grow as high as 4.9 billion before the end of the century. Researchers believe dead profiles will proliferate from non-Western countries, particularly in Asia where numbers could raise to 2 billion by 2100.
