Structural functional of families performs the four vital tasks of being the backbone of society. The first task of structural functional is socialization and this is the most important for child rearing. Parents are the ones who help children become a great addition to members of society and family socialization continues through the cycle of life. When parents teach their children they learn just as much from them as the children learn from their own parents. The second task is regulation of sexual activity, which is different in every culture where it is regulates in the interest
of maintaining kinship organization and property rights. There is a term called Incest taboo which is “a norm forbidding sexual relations or marriage between certain relatives” (pg. 515). Incest taboo still exists in every society but it does vary on which relative cannot marry. This still exists today because of biology reproduction between close relatives of any species raises the odds of producing offspring with mental or physical damage biology (pg. 515). We observe this because first it controls reproduction among close relatives for social organization and limits sexual competition in families by restricting sex to spouses. Second because “kinship defines people’s rights and obligations towards one another reproduction among close relatives would hopelessly confuse kinship ties and threaten social order” (pg. 515). Third, because it requires people to marry beyond their immediate family and this taboo serves to bring together a larger society as a kinship are linked in marriage. The third task is social placement where families are used to help maintain social organization so that parents can pass on their own social identity in the terms of race, ethnicity, religion, and social class to their children at birth. The fourth task is material and emotional security this is when you view your family as your protection, emotional support, and financial assistance.
