 Pew Research, based on a 2005 survey of 3,215 adults, estimated that three million Americans had entered into long-term relationships or marriage as a result of meeting on a dating web site.While sites have touted marriage rates from 10% to 25%, sociologists and marriage researchers are highly skeptical that valid statistics underlie any such claims.The Pew study (see table) suggested the Internet was becoming increasingly prominent and accepted as a way to meet people for dates, although there were cautions about deception, the risk of violence, and some concerns about stigmas.
