"Because women start off so low in terms of wages, having higher literacy and more skills really 29 a big
difference," said Kevin Miller, a 30 research associate at IWPR and co-author of the study.
Women need to go 31 in their training and education level to earn the same as men, Miller said.
The 32 was based on 2009 National Assessment of Adult Literacy surveys, the most recent data 33,and focused on reading skills, not writing and numeric literacy. That data was 34 from a nationally representative sample of 19,714 people aged 16 and older, living in households or prisons.
Data showed about one-third of American adults have low literacy levels, and more than 36 percent of men and 33 percent of women fall into that 35, the institute said.
