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.
Empty nest syndrome
In the last decade, the so-called "Boomerang Generation"—young adults who return to live with their parents—have changed the traditional empty nest dynamics. Factors such as the high unemployment rate in the United States and constrained job markets have been used to explain the surge in such individuals. Census data from 2008 showed that as many as 20 million 18-34-year-olds (34% of that age group) were living at home with their parents. A decade earlier, only fifteen percent of men and eight percent of women in that age range did so.
