I wonder how these numbers are derived. I'm noticing that the totals don't match up. I guess they don't include people who never modified their profiles or who never filled in the age or gender. That would make sense. Still, the discrepancy seems large. Maybe DW's "Other" and "Rather Not Say" categories are skewing the results. I think a lot of people consider it to be somewhat irrelevant to their presentation and really would rather not say. Another surprise was the age distribution. I'd expected more people in their 30s. I was less surprised that the ages stop at 55 (which only got 79 out of 39948 active accounts). My only other computer literate family member over 55 (one of my sisters in law) is ok with Facebook (which I'm not), but she hasn't been attracted by forums like DW, LJ, IJ, DJ, etc. This is not to say that she would be against the idea -- but I don't think it ever occurred to her. She knows about Facebook only because her daughter told her about it.
