Two-Parent Families (69%)Nuclear family (46%). Named after the nucleus (the tightly connected core particles of an atom), the nuclear family consists of a man and a woman and their biological offspring under 18 years of age. Almost half of all children live in nuclear families in middle childhood.Extended family (10%). If both biological parents are present and other relatives live with them (usually a grandparent, sometimes an aunt or uncle), that is an extended family. About 10 percent of school-age children live in such families.Stepparent family (9%). Divorced fathers usually remarry; divorced mothers remarry about half the time. When children from a former relationship live with the new couple, it makes a stepparent family. If the stepparent family includes children born to two or more couples (such as children from the spouses’ previous marriages and/or children of the new couple), that is called a blended family.Adoptive family (2%). Although as many as one-third of infertile married couples adopt children, few adoptable children are available, and so most adoptive couples have only one or two children. Thus, only 2 percent of children are adopted, although the overall percentage of adoptive families is higher than that.Both grandparents, no parents (1%). Grandparents take on parenting for some children when biological parents are absent (dead, imprisoned, sick, addicted, etc.).Two same-sex parents (1%). Some two-parent families are headed by a same-sex couple, whose legal status (married or not) varies. |
Single-Parent Families (31%)One-parent families are increasing, but they average fewer children than two-parent families, so in middle childhood, only 31 percent of children have a lone parent.Single mother—never married (13%). More than half of all U. S. women under age 30 who gave birth in 2010 or later were unmarried. However, by the time their children reach middle childhood, often the mothers have married or the children are cared for by someone else. At any given moment, about 13 percent of 6- to 11-year-olds are with their never-married mothers.Single mother—divorced, separated, or widowed (12%). Although many marriages end in divorce (almost half in the United States, fewer in other nations), many divorcing couples have no children. Others remarry. Thus, only 12 percent of school-age children currently live with single, formerly married mothers.Single father (4%). About 1 father in 25 has physical custody of his children and raises them without their mother or a new wife. This category increased at the start of the twenty-first century but has decreased since 2005.Grandparent alone (2%). Sometimes a single grandparent (usually the grandmother) becomes the sole caregiving adult for a child. |
| *Less than 1 percent of U.S. children live without any caregiving adult; they are not included in this table.Source: The percentages in this table are estimates, based on data in U.S. Bureau of the Census, Statistical Abstract and Current Population Reports, America’s Families and Living Arrangements, and Pew Research Center reports. The category “extended family” in this table is higher than in most published statistics, since some families do not tell official authorities about relatives living with them. |
