In the last 50 years in America the number of children living in single-mother families increased from 8% to 26%. 34% of American children now live separately from their biological father.
Last year the first study into the direct financial costs of this shift to single-mother families was released. It found that the median household income of married couples with children was $65,906 but only $27,244 for single-mothers with children. 39.3% of single mothers lived in poverty compared to only 8.8% of father-present families.
The researchers looked at 13 public welfare programmes aimed at those living in poverty, such as food stamps, energy assistance and rental assistance, and found that $100 billion per annum was being spent to support single-mother households.
It's one more reason why the traditional family should remain the ideal - the model which a society aims for and encourages.
