Work-life choices shape pay differences between the sexes

A March Pew study found that women under 30 in 10 U.S. metro areas are earning 102% to 120% of what young men earn.

Don’t expect Sen. Patty Murray, a sponsor of the Paycheck Fairness Act, to seize on this as evidence of discrimination against men. This data undermines her claims that women are systematically paid less. Rather, the data support studies finding that the biggest drivers of pay disparities are the different choices men and women make.
