Social rules or laws on marriage vary widely between countries．Some countries, still do not have a legal minimum age for marriage, which makes child macriages are very common, there．
In the Western Christian countries, a 13 -year -old is still considered a child．Even getting married in one* s late teens is not usually encouraged because married life is likely to interfere with a young woman' s education and consequently restrict opportunities in later life．And there are also physical dangers in giving birth so young．  
In Muslim countries such as Saudi Arabia, Iran and Pakistan, the age of puberty（青春期）at around 13 or 14 is the legal age for marriage, but in Turkey it is 15, and in Egypt and Tunisia, 18 the same minimum age as in many Western countries．It is argued that by allowing, earlier marriages, Islamic law is promoting stable relationships, while Western laws are encouraging promiscuity among young people．
In many countries, the trends of urbanization and education for girls have seen a drop in the number of child brides．However, early marriages continue to occur in poor rural areas．In India, for example, the legal age of marriage for a girl is 18 and to a boy, 21．Yet, according to government statistics, 18 percent of ten to fourteen-year old girls in the poor, rural state of Rajasthan in the northwest of the country are married．It is clear, then, that child marriages are connected with poverty, lack of education, rural customs as well as religion．So there don't tend to be any child marriages in urban or rich areas．
