Couples who meet online are more satisfied in their relationships and are less likely to break up than those that get together in bars, the workplace or on blind dates, according to a study.

Researchers in the US found more than one-third (35%) of couples who married between 2005 and 2012 met on the internet, with 45% of those using dating websites and 21% finding each other on social networks.

The team from the University of Chicago, Harvard University and Gestalt Research said their work – published in the Proceedings of the National Academy of Sciences journal – showed "evidence for a dramatic shift since the advent of the web in how people meet their spouse".

They questioned 19,131 respondents from across the US who got married between 2005 and 2012, and found the percentage of marital break-ups was lower for those who met their partners online (6%) than in more traditional places (8%).

Couples who got together over the web also reported greater marital satisfaction.

Most couples who met in offline environments found each other at work (22%), or through a friend (19%), while 11% met at school and 10% at social gatherings.

Of married couples those who grew up together or who met their spouse through school, place of worship or social gathering reported the highest levels of marital satisfaction, the study said, whereas those who met their spouse through work, family, bar, club or blind date expressed the lowest levels.
