The amount of education a person has plays a big role when it comes to deciding whether to make a long-term commitment to that special someone or to have a child outside of marriage, a new report says.

The 2010 edition of “The State of Our Unions” — a report on attitudes toward marriage — indicates highly educated Americans are “embracing a pro-marriage mindset” even as middle Americans lose faith in the institution. That shift resembles trends normally seen in the poor, where marriage is “fragile and weak,” according to the report, issued Monday

The findings show moderately educated women, or those with a high school diploma and some post-secondary education but no four-year degree, are choosing the single life more often these days, especially when it comes to becoming a mother.

According to the report, “in the early ’80s, 13% of babies of moderately educated mothers and 33% of babies of least-educated mothers were born outside of marriage, while 2% were born to highly educated mothers.”

In recent years, the numbers soared to 44% for moderately educated mothers and 54% for the least educated mothers. For mothers with a four-year college degree, births outside of marriage increased to only 6%.

Highly educated women also are getting married more and staying in those relationships longer, according to the report, which suggests this is a “striking reversal of historic trends”

The report cites an adherence to a “marriage mindset,” which means religious attendance and faith in marriage is now a way of life for the highly educated.

“The retreat from marriage in Middle America means that all too many Americans will not be able to realize the American Dream,” he said.

“On average, marriage plays a key role in securing the welfare of children,” said Wilcox, who added that studies show “children are much more likely to thrive if they are raised in a married home with their own mother and father.”

According to Wilcox, it’s the first to address the causes of the “observed retreat from marriage in Middle America,” and finds that shifts in marriage attitudes, increases in unemployment and declines in religious attendance are among the trends driving the retreat.

“Marriage has gotten weaker” with the decline of churches and civic group in communities, he said, adding that more outreach is needed in areas where these connections are lacking.

He also called on society to do a better job of pointing out the advantages of marriage, particularly when it comes to having children.
