The number of householders who own their own home and have minor children living there declined by 15 percent between 2005 and 2011, according to a U.S. Census Bureau report released Tuesday.

In addition, the number of households with children under 18 who had at least one unemployed parent rose by 33 percent, from 2.4 million to 3.2 million, between 2005 and 2011, the Census Bureau says in the study, America’s Families and Living Arrangements: 2012. States with a larger-than-average increase in families with an unemployed parent during that time included Nevada (148 percent), Hawaii (95 percent), Florida (93 percent), Connecticut (65 percent), New Jersey (63 percent), California (61 percent), Colorado (56 percent) and North Carolina (54 percent).

The data is from the Community Survey and the Current Population Survey. The report provides a look at the composition and living arrangements of families and households in the U.S.

“During the recession, economic well-being worsened for families with children,” says Jamie Lewis, a demographer in the Census Bureau’s Fertility and Family Statistics Branch and one of the report’s co-authors. “Home ownership among families declined and parental unemployment increased. Even after the recession officially ended in 2009, these measures remained worse than before it began.”

The report also shows trends in family structure, the Census Bureau says.

The share of households that consisted of married couples with children shrunk by half between 1970 and 2012, from 40 percent to 20 percent. At the same time, the percentage of households consisting of a person living alone climbed from 17 percent to 27 percent, the report shows.

More young people are living with their parents than at the turn of the century. For men 25 to 34 years of age, the share living in their parents’ home increased from 13 percent in 2000 to 17 percent in 2012. For women, the percent increased from 8 percent to 10 percent.

There were 605,000 same-sex couple households, including both married and unmarried couples, of whom 284,000 were male and 321,000 were female couples, the data shows.

Fifty-one percent of cohabiting couples with children had only the biological children of both partners present.

In 2012, 64 percent of multigenerational households consisted of a householder living with a child and a grandchild.

Between 1970 and 2012, the average number of people per household declined from 3.1 to 2.6.

“Over the last half-century, the trend in the U.S. has been toward smaller households, fewer family and married-couple households with children, and more people living alone,” says Jonathan Vespa, also with the Fertility and Family Statistics Branch and one of the report’s co-authors. “Many of these trends reflect a rising age at first marriage and older adults who can live in their own home for longer.”
