Unmarried mothers are now the new normal among young women in the United States. According to a Census Bureau report out this month, six out of every 10 women who give birth in their early 20's are unmarried. The report also found that - across all ages - single motherhood has increased 80 percent since 1980. So, why is the US such a difficult place for single mothers compared to other similarly industrialised nations? To discuss this, Inside Story Americas with presenter Kimberly Halkett is joined by Laurie Maldonado, co-author of the report Worst Off: Single-Parent Families in the United States; Sarah Jane Glynn, a sociologist and Associate Director of the Women's Economic Policy program at Center for American Progress; and Philip Cohen, a sociology professor at University of Maryland, who also runs a blog called Family Inequality.
