As blended families become more common, the definition of fathering extends well beyond men’s own biological or adopted children.
There are 4 million men who live with the children of a spouse or partner, according to the Men’s Fertility report out today. A subset of those men — 1.8 million — do not live with biological or adopted children of their own.
Men who live with younger children of their spouse/partner are less likely to be identified as a stepfather
Of those men, the majority — 59.9 percent — are identified as a stepfather to one or more children in the household and 40.1 percent are not.
Men who live with younger children of their spouse/partner are less likely to be identified as a stepfather: 43.8 percent of men living with children 0-5 years old and 54.7 percent of men living with children 6-11 years old.
Identifying men as stepfathers is higher when children are older. Almost 65 percent of men who live with children of a spouse or partner who are aged 12-17 (and no biological or adopted children of their own), are identified as a stepfather.
These data come from the Survey of Income and Program Participation, which collects detailed information about U.S. families’ economic well-being, as well as complete fertility histories of adults. For information about how parent/child relationships are determined in the SIPP, please see the subsection, "Measurement of Fatherhood in the SIPP" in the Men’s Fertility report.
