According to US Census Bureau, a family has been defined as a heterosexual couple and their offspring, sharing a common dwelling and dividing work by gender. In this definition, the woman has to be at home looking after her children, while the man works outside the home. In fact, according to the US Census Bureau, in 2006, only 15 percent of all American families resembled the so-called typical American family. American children live in a variety of family forms. For example, some children live in a nuclear family, many others live with a sole parent, while some others live with one biological or adoptive parent and one stepparent. Some stay with relatives or foster parents. The parents of some children are married, while others are not. Some other have same-sex parents. It is important to understand that couples without children also form a family. The trends that are being followed up these days are close buddies starting a "voluntary kin" movement, sharing households and wills, Atheists marrying Baptists, Democrats joining Republicans, Blacks tying it with Whites, men getting married to men, and women to women. It is, therefore, vital to learn about various family structures and constructs, and to understand that different families deal with different strengths and values, as well as different needs and issues. 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 esteem by society, known as the ideal one to raise children. It is believed that children belonging to the two-parent structure families are stable. However, with changing times, it has been observed that the nuclear structure has become less prevalent. A single parent is the one who looks after the child solely, without the assistance of other (usually biological) parent. The child can be by birth or adoption. Single parent families are often the result of death of a spouse, separation, or divorce of a couple with children, or child abuse/neglect. There's another case wherein adults who want children but do not have a partner, adopt kids―usually termed as single parent adoption. This single parent is also called the primary caregiver, for parenting the child solely for majority of the time. Gobs of grandparents are raising their grandchildren today. Reasons can be varied, like parents' death, or unfit parents, or when both the parents work. Many grandparents need to go back to their working phase for finding a source of income to raise their grandchildren. Two separate families blending together to form a single unit leads to the creation of a blended or step family. Step families are becoming mundane in America. Over half of the marriages end in divorce, and many of these individuals prefer getting remarried, thereby creating the step family. It can consist of a new husband and a wife, and their children from previous relationships or marriages. In blended ones, biologically unrelated children may live together. These families have more problems, their kids do not get comfortable, and have adjustment and discipline issues. They need to learn to work together. Also, the parents should work with their exes for smooth running of their current family. An extended family is the one that enlarges beyond the immediate family; which can consist of grandparents, uncles, aunts, cousins, and likewise, living under a single roof. There are certain pros 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. 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. The children that were given up at birth, abandoned, or were unable to be taken care of by their biological parents are given to foster houses or child care institutions. The children referred by the courts or government agencies are being raised and taken care of by the institutional child care workers or simply by their foster parents. Here, the parents live and work in different cities or states. The primary residence is provided by one parent, while the other parent comes home for shorter durations, like on weekends and holidays. This can occur due to varied reasons. For instance, finding professional jobs in different cities, or one or both parents may have military obligations that require them to stay away from their families for certain time periods. In this kind of family, a man and woman live together, but are unmarried. If they have children, chances are that one of the adults is a biological or adoptive parent. The cohabitation lifestyle is becoming more popular. People prefer this for it is cheaper and simpler. Owing to the hike in divorce rates, the desire to get married isn't attractive among couples who aren't sure of their long-term plans. Studies say, the number of heterosexual unmarried couples in the US has increased tenfold, from about 400,000 in 1960 to more than five million in 2005. Families in which the couples are Lesbian or Gay choose to raise children. They may have children from ex-heterosexual relationships, or may have been adopted or conceived using assisted reproductive technologies. There can be cases like one parent being the genetic one and the other parent adopting the child. Other times, one is the gestational parent, while the other is the genetic parent. According to reports, there are around 66% of female same-sex couples and 44% of male same-sex couples who live with children under 18 years of age. Some of the influences that shape the dynamic African-American families are racism, poverty, migration during 20th century, or recent immigration. Generally, these are extended families, and so are more hierarchical, and likely to be strict, following a certain standard in behavior and discipline. The African-American children are mostly in contact with their male cousins, uncles, and other men in their community, even if their biological father is not present. ● Average Family Size: Number of all the people in families divided by the total number of families is the Average Family Size.

The American society tends to promote the traditional family through various media; children who fall under other categories may feel that theirs is not a real family. They may get self-conscious about being part of a family which is "different". In some cases, they might face social challenges too. As a parent of the unconventional family, you can help your children cope up with complicated situations by encouraging open discussions. It is crucial to help children understand that the family structure doesn't matter as much as the love and affection shared by members of the family, living under a roof.
