Demographic and Socioeconomic Characteristics of Nonresident Parents [October 18, 2021] [open pdf - 2MB]
From the Introduction: "In the United States, there were more than 9.7 million parents who were not living with one or more of their children under age 21 in 2018. Federal policymakers have expressed interest in these 'nonresident parents' out of concern for the wellbeing of the parents and the impacts for children who live apart from one or more of their parents. (For the purposes of this report, a nonresident parent is a person 15 years or older who does not reside for a majority of nights in the same household as one or more of his or her biological, adopted, or stepchildren under age 21. ) About 21.9 million (26%) children under age 21 had a parent who lived outside their household in 2018. Like all parents, nonresident parents can make important emotional, time, financial, and other contributions to their children's lives."
