Yesterday evening I reported on Comscore’s data reporting a massive increase in Facebook’s user base. I commented on one aspect of the data that was interesting. According to the statistics, over 50% of Facebook users were 35 and up. Really? That hardly makes sense, but I seemed to gloss right over it. Then today, Alec Saunders asked the same question. Why is this data so skewed? Even data released by Facebook a matter of months ago showed this demographic accounts for around 750,000 users. The Comscore data is blatently wrong. It suggests that a year ago, over 5 million users older than 35 visited the site. If that traffic stayed steady for a year, less than 1.5% of those visitors became registered users. That makes no sense whatsoever. There has been discussion within the blogosphere of the need for accountability for the internet data companies (primarily Comscore and HitWise), and this surely adds fuel to the fire. The bottom line is that these statistics are totally wrong. Comscore better come up with an explanation pretty quick since their integrity is on the line.
