Too much age difference may not be good for your marriage: study

Washington: Men and women may tend to experience greater marital satisfaction with younger spouses, but according to a recent study, the contentment fades away over time.

The findings also suggest that marriages with large age gaps are less resilient in the face ofeconomic downturns as compared to their similarly-aged counterparts.

Research from University of Colorado at Boulder, US revealed that that men reported greater marital satisfaction when paired with a younger spouse, especially in the early years of marriage.

Study author Terra McKinnish said that men who are married to younger wives are the most satisfied and men who are married to older wives are the least satisfied.

"Women are also particularly dissatisfied when they're married to older husbands and particularly satisfied if they're married to younger husbands," McKinnish added.

That initial satisfaction erodes rapidly, however, after 6-10 years of marriage for the couples with a big age gap between the partners.

"Over time, the people who are married to a much older or younger spouse tend to have larger declines in marital satisfaction over time compared to those who are married to spouses who are similar in age," McKinnish noted.

One mechanism for this decline could be how the age difference between spouses affects the couple's ability to respond to negative economic shocks, such as a job loss, McKinnish said.

"We looked at how couples respond to negative shocks and in particular, if they have a major bad economic shock or worsening of their household finances," she said.

The nationally representative sample was initially comprised of 7,682 households containing 1,9,914 individuals. The participants are re-surveyed every year with questions that measure various aspects of life satisfaction.

The results suggested that when couples have a large age difference, they tend to have a much larger decline in marital satisfaction when faced with an economic shock than couples that have a very small age difference.

A possible explanation for this, McKinnish said, is that similarly-aged couples are more in sync on life decisions that affect both partners (having children; general spending habits) and thus, may be better equipped to adjust to a negative financial shock.
