If you’re in the U.S. and are using a social network like Facebook, MySpace or LinkedIn, chances are you’re more affluent and more urban than the average American according to Nielsen Claritas, which provides in-depth segmentation analysis of consumer behavior. "The rising popularity of these sites and the deep engagement consumers have with them has advertisers and marketers asking for more and more detail as to which lifestyles should be targeted for their online advertising and promotions," said Wils Corrigan, AVP, Research & Development, Nielsen Claritas.
