According to a study done by the Nielsen Company, Facebook and Twitter users are wealthier and than their MySpace counterparts living on the other side of the railroad tracks. Computer World notes, "The survey, which studied the top seven social networking sites, showed that Facebook users generally have an 'upscale profile,'" going on to point out, "Nielsen also noted that people who are more affluent than the other two-thirds of the population are 25% more likely to use Facebook than those in the the lower third. And conversely, those in the bottom third of the financial chart are 37% more likely to use MySpace than those in the top third."

But while MySpace flounders in the affluent area, they're more than makeup by having younger users. A July '09 report done by iStrategyLabs shows says that "[t][he number of 55-and-older Facebook users showed staggering growth -- 513.7% -- in the last six months." Twitter has also seen similar growth within the of-a-certain-age sect.
