According to a new study, a record four out of ten households have mothers as the sole or primary source of income in the family. That is compared to 1 out of 10 households in 1960.

Breadwinner moms are made up of two groups: 60 percent are single mothers and 40 percent are married women who have a higher income than their husbands.

"Over 50 percent of the people graduating from college are now women," said Howard Hitzel, Psy.D., President of Lake Shore Behavioral Health. "Now women are becoming well educated and well trained for the workforce and they are finally being compensated well for the work they are doing."

The economy is also a factor when it comes to the increased number of mothers in the working world. In many families, both parents are required to work in order to make ends meet.
