"Our analysis is quite disturbing, especially when you consider how more and more families are depending on a woman's paycheck as the primary source of income in these tough economic times. Consequently, the issue of pay equity takes on an added sense of urgency. This is just one of the reasons why we're urging the Senate to join the House and pass the Paycheck Fairness Act," AAUW Executive Director Linda D. Hallman, CAE, said in a press release announcing its findings.

The AAUW (www.aauw.org) report uses the most recent data from the U.S. Census Bureau’s American Community Survey (2007).
