The family dynamic is changing with few children living in a two-parent home. According to the U.S. Census Bureau’s annual America’s Families and Living Arrangements report, only 75 percent of children under the age of six lived with two parents. This contrasts with children aged 12 to 17 years old who lived with two parents at a rate of 68 percent.

In 2023, the majority of parents were married in a two-parent household and 3.2 million children lived with cohabiting parents. This is an increase from 2.2 million in 2007.

In 2023, there were just over 38 million one-person households, making up 29 percent of all households, an increase from 13 percent in 1960. Nearly one-quarter of children under the age of 15 were living in an opposite-sex-married family with a stay-at-home mom, compared to just 1 percent with a stay-at-home father.

Overall, the number of families with children is on the decline, falling from 48 percent in 2003 to 39 percent in 2023.

Meanwhile, the number of adults, 15 and over who have never been married, rose from 23 percent in 1950 to 34 percent in 2023. The median age to get married in the U.S. has risen from 23.7 to 30.2 for men and 20.5 to 28.4 for women.

More people are “living at home” after they turn 18, with 56 percent of adults between 18 and 24 living in their parent home and 16 percent between the ages of 25 to 34.
