Nuclear Family (The Formal Type!) A nuclear family is considered to be the most traditional family,consisting of a mother,a father,and the children.This family type holds a lot of respect by society,known as the ideal one to raise children.It is believed that children belonging to the two-parent structure families are stabe.However,with changing times,it has been observed that the nuclear structure has become less popular. |
Single Parent Family (Mostly the Breadwinner Parent!) A single parent is the one who looks after the child without the assistance of the other parent.The child can be by birth or adoption.Single parent families are often the result of death of another parent,divorce of a couple with children,or child abuse.There's another case where adults who want children but do not have a partner,adopt kids-usually termed as single parent adoption. |
Grandparent-led Family (The Wrinkled Affection!) Lots of grandparents are raising their grandchildren today.Reasons can be varied,like parents'death,or unfit parents.Many grandparents need to go back to their working phase for finding a source of income to raise their grandchildren. |
Blended (混合的) and Step Family (Sometimes the Black Sheep Type!) Two separate families blending together to form a single unit can lead to the creation of a blended or step family.Step families are becoming common in America.Over half of the marriages en in divorce,and many of these individuals prefer getting remarried,thereby creating the step family.It can consist of a new husband,a wife,and their children from previous relationships or marriages.These families have more problems because their kids do not get comfortable,and have adjustment and discipline issues. |
Extended Family (The More,The Merrier!) An extended family is the one that enlarges beyond the immediate family,which can consist of grandparents,uncles,aunts,cousins and so on,living under a single roof.There are certain advantages to such family groups.The members (especially children) feel more secure and safe due to elder guidance and sharing of resources during a crisis,and have more role models to help maintain desired etiquette and values. |
Childless Family (Child-free Companions!) While most people think of family as including children,there are couples who are very young and intend to have children later,or those who cannot,or choose not to have children.This type is also called the"forgotten family",as it does not meet the set in definition of family.It has been observed that many of the childless families own pets or have external contacts with their nieces and nephews as a substitute for having their own children. |
