While the U.S. marriage rate is at its lowest level since 1920, New Jersey's divorce rate is also the lowest in the country, according to a recent study.

In the study from Bowling Green's National Center for Family and Marriage Research, the rate stands at 31.1 per 1,000 females, its lowest rate since 1920, when the rate was 92.3. But here in New Jersey, the U.S. Census Bureau reports the state has the lowest divorce rate in the country.

New Jersey marriage expert Marty Tashman thinks it's due in part to better educated residents who have more money.

"I think the education level, the wealth level and the number of foreigners in New Jersey in particular might be some of the reasons why we are making some divorce lawyers unhappy," Tashman said.

Tashman also believes ethnic diversity lends itself to more traditional marriage values about marrying and staying married. He also suggests many of the portrayals in popular media these days do not lend themselves to making an impression on young people about the permanency of the marriage institution.
