Single parent
In the United States, 83% of single parents are mothers. Among this percentage of single mothers: 45% of single mothers are currently divorced or separated, 1.7% are widowed, 34% of single mothers never have been married. Although decades ago, having a child outside of marriage and/or being a single mother was not prominent. Census information from 1960 tells us that in that year, only nine percent of children lived in single parent families. Today four out of every ten children are born to an unwed mother.
Attachment parenting
In 2014, a team of researchers at the University of Mary Washington showed in a study that 23% of mothers who believe in "intensive motherhood" suffer from signs of depression; among average mothers, this applies only to 6.7%.
