Single-father households, grandparents raising grandchildren and same-sex partners raising kids are among the fastest-growing types of households with children in Oklahoma.
The traditional, nuclear family unit of husband, wife and kids accounted for more than 21.4 percent of all Oklahoma households in 2010. That's down from 24.7 percent a decade ago.
The number of nuclear family households fell 5.9 percent in the past decade to 312,372, according to an analysis of census data by The Oklahoman.
Among other findings:
• Married couples with no children at home accounted for 28.1 percent of households in 2010, up 6 percent.
• More than 79,580 Oklahoma children were being raised by a grandparent in 2010.
• Unmarried partner households jumped by 63 percent in the past decade. They now make up 5.9 percent of all Oklahoma households, up from 3.9 percent of households in 2000.
• There were more than 9,800 same-sex households in 2010, an increase of 70 percent from 2000. Same-sex households make up a small part, 0.67 percent, of all households in the state.
“There's lots of evidence that we're seeing a growing diversity in the kinds of households and families in Oklahoma,” said David Blatt, director of the Oklahoma Policy Institute. “Overall, we're seeing less married couples with children families in the state and more children being raised by other family members and more straight couples living together outside of marriage.”
