Gender is a socio-cultural concept. According to the UNICEF regional office of South Asia (2017) "Gender includes the expectations held about the characteristics, aptitudes and likely behavior of both women and men (femininity and masculinity)". Gender roles and responsibilities are learned or acquired over some time. These roles and responsibilities are contrasts within and among the cultures and they can be changed. The social and structural systems such as class, caste, ethnicity, age, cultural practices, political and economic status, and geographical location, physical and mental state determine or modify the roles but biologically there are no such predetermined roles or characteristics.
