Iowa Gender Wage Equity Study, 2008

In 1993, Iowa Workforce Development (then the Department of Employment Services) conducted a survey to determine if there was a gender gap in wages paid. The results of that survey indicated that females were paid 68 cents for every dollar paid to males. Another study was conducted in 1999 which found that females made approximately 73 cents for every dollar made by males in Iowa. These calculations took into account the average number of hours respondents worked weekly. In January 2008, Iowa Workforce Development (IWD) was contacted by the Iowa Commission on the Status of Women (ICSW) to request that IWD conduct research to update the 1999 gender wage equity study to determine if the wage disparity between males and females has changed since the 1999 study. This study was completed by IWD using 2007/2008 Laborshed data consisting of responses from 5,669 employed respondents. Of the respondents, 59.6 percent (3,379) were female, 40.3 percent (2,285) were male, and 0.1 percent (5) refused to identify their gender. Statewide sampling was provided by the University of Northern Iowa’s Institute for Decision Making based on the population per ZIP code. The results of the survey show that females who are paid an hourly wage earn 21.8 percent (78.2 cents for every dollar) less than males earn and females who are salaried earn 21.6 percent less than males. Additional survey results detail the occupational categories, industries and the education and experience levels. All of these characteristics contribute to the disparity.
