The gender pay gap is shrinking, but at this rate, it might not vanish until 2070. Women in the U.S. on average earn $0.79 for every $1 their male colleagues make, according to a new report by the job search and salary tracker site Glassdoor. The study, released Tuesday, calculated the adjusted pay gap, which accounts for variables like age, education, and industry, at 4.9 percent, down 0.5 percent from three years ago. Meanwhile, the unadjusted pay gap in the U.S. is 21.4 percent, and while that figure has shrunk by 2.7 percent since 2016, it won't fully close for another 51 years unless employers do more to fight pay disparity. The report comes before Equal Pay Day on April 2, a date determined by the National Committee on Pay Equity that symbolizes how far into the year women must work to earn what men made in the previous year.
