Harris Interactive / eHarmony Study Finds an Average of 236 eHarmony Members Marry Every Day eHarmony Now Accounts for More Than 2 Percent of All New U.S. Marriages

PASADENA, Calif., July 28, 2008—New research conducted by Harris Interactive finds that, on average, 236 eHarmony members marry every day in the United States as a result of being matched on eHarmony. This number represents a 162 percent increase in “I do’s” since 2005, when Harris Interactive conducted a similar phone poll that found an average of 90 eHarmony members married every day. Based on the research, eHarmony marriages accounted for 2 percent of new U.S. marriages during the study period, up from 0.79 percent of marriages in 2005.

“Many eHarmony members find long-term, satisfying relationships that lead to marriage,” said Greg Waldorf, CEO of eHarmony. “These results from a credible market research company like Harris Interactive validate and distinguish our scientific approach and compatibility matching models.”

“We were pleased to work with eHarmony and utilize our Internet research expertise to help them better understand their members’ behavior,” said Dan Hucko, senior vice president of corporate communications at Harris Interactive.

eHarmony’s scientific approach and emphasis on helping people find compatible long-term partners makes it different from other online dating services. In addition to its ongoing research in the United States, the company has also conducted extensive marriage research in international markets in order to tailor its compatibility models.

“eHarmony was the first online relationship service to use relationship science to develop its compatibility matching models,” noted Dr. Galen Buckwalter, chief scientist of eHarmony. “We are committed to investigating and understanding what makes marriages successful through further rigorous scientific research.”

The Harris Interactive/eHarmony study was conducted through a nationwide online survey using a representative sample of 7,135 Americans aged 20-54 who were married between April 1, 2006 and March 31, 2007. Data were weighted to be representative of recently married U.S. residents within that age range. Respondents were about equally divided between men (49 percent) and women (51 percent). U.S. Census Bureau data were used to extrapolate the number of couples nationwide who married after being matched by eHarmony. The overall margin of error is 0.51 percent.
