Historically, functionalist sociologist George Peter Murdock ("Social Structure", 1949) states this: "The family is a social group characterized by common residence, economic co-operation and reproduction. It includes adults of both sexes, at least two of whom maintain a socially-approved sexual relationship, and one or more children, own or adopted, of the sexually cohabiting adults."
Obviously, this definition of a family is based on an ancient social structure of what constitutes a family. In fact if, Murdock were to quote this in today's society, society would not accept him socially as this is not a true representation of a 21st Century family structure. In other words this is not a true definition of a family because of the many family types that are presently socially accepted, Murdock would be criticized for this comment as he pinpoints only one type of family that is accepted as a family. In fact, in today's society, the functions of the family are being performed by a many different family structures, aforementioned. However the feminists say that the nuclear family is designed to suit men's needs as married men get a servant and sex slave. Both men and women learn what to expect from marriage during socialization, so one solution may be to change the way in which children are raised. Feminists also argue that the decline in marriage is down to women realizing that they are being exploited in the nuclear family home and that they are just not willing to tie themselves down (White & Klein, 2008, p.35) .
