14.2.1 Single Parents, Blended Families, and Foster Families

Single-parent households are on the rise. In 2017, 32 percent of children lived with a single parent only, up from 25 percent in 2008. Of that 32 percent, 21 percent live with their mother. Four percent live with their father, which is a percentage that is growing in share; in 1968, for example, only one percent of children lived with a solo father, and three percent lived with a solo father in 2008 (Livingston 2018).

About 16 percent of children are living in blended families, those with step parents and/or step-siblings. This number has remained relatively stable since the 1980s when the Census Bureau began reliably measuring it. Four percent of children live in families with couples who are not married. (That number is partially composed of parents in same-sex relationships who were previously prohibited from getting married.)

In some cases, parents can no longer care for their children. In 2018, three million children lived with a guardian who was neither their biological nor adoptive parent. The causes range from parental mental health issues, drug use, or incarceration, as well as physical or sexual abuse of the children by the parent, or abandonment by the parent. The wide array of causes leads to a similarly wide array of arrangements and types of people and organizations involved. About half of these children live with grandparents, and about 20 percent live with other relatives (ChildStats 2019). Sometimes a grandparent or other relative temporarily assumes care of children, perhaps informally, while other times the arrangement is longer term and the state or city child welfare or similar department is involved.

25 percent of children who do not live with an adoptive or biological parent live with nonrelatives, including foster parents, temporary guardians, or people in other types of relationships with the child or the child's parents. Non-relative foster parents are state-certified adults, who care for children under the guidance and supervision of a relevant agency. Foster parents comply with guideline and are provided with financial support for the children they care for. (Sometimes the term foster parent refers to a relative who cares for the children under agency guidelines, and sometimes these "kinship" foster parents are also provided financial support.)

When children are placed into foster care or other non-parental care, agencies and families usually do their best to keep siblings together. Brothers and sisters usually provide each other with someone to navigate social challenges and provide continuity over time. Studies have shown that siblings placed together show more closeness to their foster caregivers and like living in the foster home more than those not placed with a sibling (Hegar and Rosenthal, 2011). Separating siblings can cause them to worry about each other or their birth families, and slows acceptance of their new home (Affronti, Rittner, & Semanchin Jones, 2015).

Siblings sometimes play more of a parental role themselves, especially when there are large age gaps or if there are very young children involved. These older siblings may take on some parental responsibilities during a divorce or when children are sent to live with others. "Parentified" siblings may have trouble navigating the complexities of parental roles when they themselves are often still very young. These experiences can actually be traumatic and lead to compulsive disorders as well as lifelong issues with relationships and self-care (Lamothe 2017)

Changes in the traditional family structure raise questions about how such societal shifts affect children. U.S. Census statistics have long shown that children living in homes with both parents grow up with more financial and educational advantages than children who are raised in single-parent homes (U.S. Census 1997). Parental marital status seems to be a significant indicator of advancement in a child’s life. Children living with a divorced parent typically have more advantages than children living with a parent who never married; this is particularly true of children who live with divorced fathers. This correlates with the statistic that never-married parents are typically younger, have fewer years of schooling, and have lower incomes (U.S. Census 1997). Six in ten children living with only their mother live near or below the poverty level. Of those being raised by single mothers, 69 percent live in or near poverty compared to 45 percent for divorced mothers (U.S. Census 1997). Though other factors such as age and education play a role in these differences, it can be inferred that marriage between parents is generally beneficial for children.
