More US wives cheating on husbands

The number of American women cheating on their husbands has considerably increased in the past two decades, a report has revealed.

According to the National Opinion Research Centre's General Social Survey, the percentage of wives having affairs rose by almost 40 per cent in the past two decades to 14.7 per cent in 2010, the Sydney Morning Herald reported.

However, the number of men admitting to extramarital affairs remained constant at 21 per cent.

The trends reveal that wives with their own jobs have less to lose on the economic front from a divorce, and social media have made it easier to have affairs.
