The Washington Post on President Obama’s claim that women only earn 70 cents to each dollar earned by men (later “corrected” to 77 cents):
We were struck by the disparities in the data when we noticed that a news release by Sen. Barbara Mikulski (D-Md.) trumpeted the 77 cent figure, but it included a link to a state-by-state breakdown that gave a different overall figure: 81 cents.
What’s the difference? The 77 cent figure comes from a Census Bureau report, which is based on annual wages. The BLS numbers draw on data that are based on weekly wages. Annual wages is a broader measure — it can include bonuses, retirement pensions, investment income and the like — but it also means that school teachers, who may not work over the summer, would end up with a lower annual wage.
In other words, since women in general work fewer hours than men in a year, the statistics may be less reliable for examining the key focus of the legislation — wage discrimination. Weekly wages is more of an apples-to-apples comparison, but as mentioned, it does not include as many income categories,
The gap is even smaller when you look at hourly wages — it is 86 cents vs. 100 (see Table 9) — but then not every wage earner is paid on an hourly basis, so that statistic excludes salaried workers. But, under this metric for people with a college degree, there is virtually no pay gap at all.
There are so many different ways of slicing the data that you can “prove” almost any proposition. President Obama also claimed that African American women and Hispanic women’s wages are even worse: “64 cents on the dollar for African American women and 56 cents for Hispanic women.”
Not only did the White House pick the statistic that makes the wage gap look the worst, but then officials further tweaked the numbers to make the situation for African Americans and Hispanics look even more dire.
The BLS, for instance, says the pay gap is relatively small for black and Hispanic women (94 cents and 91 cents, respectively) but the numbers used by the White House compare their wages against the wages of white men. Black and Hispanic men generally earn less than white men, so the White House comparison makes the pay gap even larger, even though the factors for that gap between minority women and white men may have little to do with gender.
