The increase in 25 to 34 year olds living in their parents’ home began before the recent recession, and has continued beyond it.
- In general, the percent of all households that contain just one person has risen over the last half of the 20th century and into the 21st century. The percentage of such households rose from 13 percent in 1960 to 28 percent in 2011. While the percentage may not differ significantly from one year to the next, the overall trend has been an upward one. The percentage did decline, however, from 2008 to 2010. (See Figure 4.)
- Of the 74.6 million children younger than 18 in 2011, most (69 percent) lived with two parents, while another 27 percent lived with one parent and 4 percent with no parents. Of those children who lived with two parents, 92 percent lived with two biological or two adoptive parents.
- Among the children who lived with one parent, 87 percent lived with their mother.
- Of the children living with no parents present, 57 percent lived with at least one grandparent.
- In 2011, 10 percent of children under 18 lived with at least one grandparent. Seventy-eight percent of these children also lived with at least one parent.
- Of the 67.8 million opposite sex couples who lived together, 89 percent were married couples, while the remaining 11 percent were unmarried.
- In 2011, there were about 7.6 million unmarried couples living together.
- In 2011, married couples with children made up 20 percent of all households, half what they were in 1970 (40 percent). (See Figure 3In 2011, 23 percent of married couple family groups with children younger than age 15 had a stay-at-home mother. This proportion decreased in the last few years during the recession. In 2007 — before the recession began — the corresponding figure was 24 percent. .)
