.- One in two: that is the current number of children in the U.S. who are being raised by both their married biological parents throughout their childhood.

“This figure is based on the proportion of 17-and-18-year-old high school students who were reported to be living with both their married birth mothers and biological fathers in 2016,” noted a report issued by the Institute for Family Studies.

“The fact that they were still living in such families at the culmination of their schooling means that the vast majority of them grew up in them since birth,” the report continued.

The Feb. 27 report was authored by researchers Nicholas Zill and W. Bradford Wilcox, and published by the Institute of Family Studies. It analyzed data from a survey released by the U.S. Department of Education.

With lower marriage rates in the U.S., declining rates of children living with married parents are not a surprising find for researchers.

However, the study considered the numbers in light of several different factors, particularly including education and race.

“Among high school seniors whose parents or guardians had a college education or more, 64 percent lived with married parents throughout childhood in 2016,” the study noted.

“The more education a woman or man has, the more likely she or he is to get married and stay married when raising children.”

Only 29 percent of children whose parents or guardians had less than a high school education still lived with married parents from their birth through the end of high school.

Race was also examined in the study. Asian-American children were found to be the most stable group, with two-thirds of them living with married parents throughout their childhood. Fifty-eight percent of white children could say the same.

However, less than one-quarter of African-American children experienced a married, two-parent household, and only 45 percent of Hispanic children grew up with married parents. The study noted an additional multiracial group, of which 35 percent experienced a childhood with both married parents.

The report also examined the 50 percent of children who did not grow up with both married parents.

Overall, 23 percent of children were raised by only their birth mother. Eleven percent were raised by a birth parent and a stepparent. Six percent were raised by their birth father only. And the other 10 percent were mixed between grandparents, foster care, cohabiting birth parents, adoption, and same-sex couples.
