Oklahoma women who were full-time wage and salary workers earned 21 percent less than men on a weekly basis last year, according to estimates released this week by the U.S. Bureau of Labor Statistics.
Women across the state had median weekly earnings of $601, or 78.6 percent of the $765 median weekly earnings of men in 2011, the bureau reported.
The median is a halfway point — half of a group of numbers is more and half is less.
The report shows that Oklahoma had an annual average of 1.2 million workers last year, and that 534,000 were women and 703,000 were men. For all workers, median weekly earnings last year were $677, according to the bureau's data.
The ratio of Oklahoma women's earnings to men's earnings has fluctuated over the years, from about 75 percent from 2004 to 2008, to a series high of 87.2 percent in 2009. Since then the ratio of women's earnings has remained around 78 percent, the bureau reported.
The report uses estimates obtained from the Current Population Survey, a national monthly survey of about 60,000 households conducted by the U.S. Census Bureau for the Bureau of Labor Statistics. The earnings data are collected from one-fourth of the Current Population Survey monthly sample.
