Clearly, the 2.5 percent gap between the male and female unemployment makes for an interesting set of data points. It’s the largest gap since World War Ⅱ, and economists blame it on the huge layoffs in manufacturing and construction, where men made up roughly 70 and 85 percent of the workforce.

The wage gap between the genders has largely been static during this decade. Still, roughly 35 percent of women now bring home at least half of their family’s income.
College-educated women without children have made the largest advances in terms of closing the income gap, but women with less schooling and those with small children still earn substantially less than men. "Maybe this will be an opportunity for people to rethink paid employment, particularly now that families are dependent on the earnings of the wife," says Eileen Appelbaum, an economist and director of the Center for Women and Work at Rutgers University. "A lot of the jobs out here or women are in nursing or as home health aides. Those are not jobs that pay family-sustaining wages. \
