A recent study in Australia shows that certain factors need to be present for a successful and long-lasting marriage. In addition to love, factors such as age difference, financial situation and living habits will have an impact on whether both parties can grow old together.

　　Reuters reported on the 14th, the Australian National University researchers from 2001 to 2007 tracking survey of nearly 2,500 married couples or unmarried cohabiting couples, to analyze the impact of the relationship between the two sides can be a long time some of the factors.

　　One of the factors is the age gap between the two sides. The study shows that if the husband is nine years older than his wife or more, the couple is twice as likely to divorce as others.

　　Factor number two is children. Among the respondents, the divorce rate was 20% for couples who had never had children or had children from a previous marriage, compared to 9% for couples who had children after marriage.

　　The third factor is economic status. If the economic situation is poor or the man is unemployed, 16% of the partners end up splitting up. In contrast, only 9% of those in a better financial situation break up.

　　Factors such as the marital status of the parents and whether or not the partner smokes also have an impact on whether or not the marriage will last.

　　Factors such as the number of children born after marriage, the age of the children, the wife's job situation and the length of service of both partners did not have a significant effect on the longevity of the marriage.
