Gender inequality, or in other words, gender discrimination refers to unfair rights between male and female based on different gender roles which leads to unequal treatment in life. The term gender inequality has been widely known in human history but not until the beginning the 20TH century has the transformation of gender relations become “one of the most rapid, profound social changes” (Wright & Rogers 2009).

And at the same time, the position of men and women were generally set. The growth of this situation has been obviously seen. According to a survey in America, female’s salary at work is 75% as LOW as male’s. Coming back to last century, at work, when men were paid 1 DOLLAR, the amount that women RECEIVED was just 58 cents, in accordance with the law in 1963 (Tran 2012) . And in Vietnam, gender inequality is shown in the difference between two genders in the number of babies. Statistics of Ministry of Planning & Investment in 2010 REPORTED that there were 110.6 new-born boys out of 100 new-born girls which was much higher than in the past.
