I did some rough-and-dirty calculations based on US census data (https://www.census.gov/quickfacts/fact/table/US/RHI725219) and the 83-cent statistic in the article. Turns out non-Latina white women actually earn _more_: about $1.03 for every $1.00 earned by non-Latino white men.
A lack of transparency will do more to hurt gender and racial equality in the long run. It's better to leave the statistic in and explain why the numbers are as they are instead of turning a blind eye.
