For Murdock, family is a multi functional, indispensable and an inevitable social institution in society. Murdock claims that universal functions of the family are (a) sexual (b) reproductive, (c) economic and (d) educational functions. Murdock thinks that these functions are universal because without sexual and reproductive function, the society cannot exist; without economic function (for example, preparing and providing food), the society cannot subsist; and without the educative function, in the meaning of socialization, there would be no human culture.
