The secret of a happy marriage? Find a man 5 years older who hasn’t been hitched before
According to the study, the couples with the best chance are those where a woman with a superior education marries a man who is five or more years older than herself.
Neither should be a divorcee.
By comparison, a marriage where a woman partners an equally poorly educated male divorcee who is five or more years her junior is up to five times more likely to fail.
The study is good news for David Cameron, 43, and wife Samantha, 38. Meanwhile, US President Barack Obama, 48, and wife Michelle, 45, may have only a three-year difference in age but have been married for 17 years.
The research, called Optimising The Marriage Market, appeared in the European Journal Of Operational Research, which usually analyses business decisions.
Using the data collected about their age, education, nationality and previous relationships, they found the factors that many of those who broke up had in common.
Psychologists then analysed the importance of each factor to build up profiles of an ideal marriage and a nightmare couple. With age, they found that if the wife is five or more years older than her husband, they are more than three times as likely to divorce than if they were the same age.
Couples where the wife is five or more years younger than the husband are the least likely to hit trouble, with their divorce rate six times less.
With education, couples in which neither partner has studied much are the most likely to break up. Those where both are well educated are half as likely to divorce.
If the woman is better educated than the man, they are eight times as likely to stay together than the uneducated couple, and three times more secure than if the husband were more of a bookworm than the wife.
