Sex and gender are concepts that are essentially similar, they both distinguish between men and women. That's only if sex emphasizes the biological difference, then gender is a social role.
The concept of gender
If we turn to the definition of gender, then we can imagine the essence of this concept somewhat wider. Gender is sex from the social point of view, that is, gender as an indicator that determines the behavior and place of a person in society, as well as how certain behaviors will be perceived by society. The concepts of sex and gender are closely intertwined, and the second focuses on the role of man in the society, as well as on his behavior that determines the relationship with other members of the society.
Thus, sex and gender are one concept, only gender emphasizes its social side. It is important to understand that in a broad sense, female gender includes not only women, but also men who are characterized by female social behavior (for example, people of non-traditional sexual orientation). In this regard, gender and identity are linked more strongly than gender and gender.
Gender and family
One of the problems of gender is different gender stereotypes. The society seeks to give an assessment of the individual based on how she copes with her social role. As it is easy to see, the psychology of gender is that a man is evaluated from the point of view of social and financial achievements, and a woman - from the point of view of acquiring her family and children. That is, even a successful woman managing corporation is considered a failure if she does not have a family. For a man, this situation will not cause inconvenience or condemnation.
However, in the modern world gender roles are not always distributed in the classical way in the family. There are alliances in which a woman earns money, and a man is engaged in home and children. In 30% of families, women earn more than their husbands, but this fact is not noted at all - and the reason for this is gender stereotypes.
