From the press release:
On the eve of International Women’s Day, women workers in the United States are facing a larger wage gap that has grown for women in all major race and ethnic groups, according to analysis by the Institute for Women’s Policy Research (IWPR). The ratio of women’s to men’s median weekly full-time earnings was 80.9 percent in 2012, a decline of more than one percentage point since 2011 when the ratio was 82.2 percent.
Women’s earnings may have been hurt by budget cutbacks and the loss of public sector jobs at the local and state level. These are often medium and higher skilled jobs with smaller wage gaps than lower-paying industries, such as retail and hospitality, which saw strong job growth in 2012.
