Women employees at the White House get paid 20 percent less than male employees, a study has revealed.

The analysis by Roll Call also showed there are more male employees in the White House than women — approximately 200 men as compared to 174 women.

The annual report to Congress on White House office personnel, released Friday, showed women earned an average of $84,500 a year as compared to men who earned $105,000. According to the statistics, women, on an average, earned about $20,995 less compared to men.

The report also adds that gender pay gap among the White House employees has barely changed throughout the past three presidential administrations.

The report also added that the analysis omitted three White House employees from the survey as they do not take home any salary — President Donald Trump’s daughter Ivanka Trump, her husband Jared Kushner and a former Baltimore real estate developer, who has not been publicly identified.

A study conducted by the Pew Research Center showed that the gender gap in pay among young workers in the U.S. has narrowed since 1980. A study conducted in 2015 suggests that women earned 83 percent of what men earned on an average.

The difference in the incomes of men and women staffers at the White House is primarily because of the fact that women end up taking low-ranking jobs, reported CNN. The report also added that Mark House, the White House senior policy advisor, is the highest paid staffer, earning $187,100 a year. Other highly paid White House staffers include John Destefano, Stephen Miller, Reince Priebus, Sean Spicer, according to Quartz.

However, as there are exceptions everywhere, some of the women staffers at the White House, too, get paid as much as men. These women include senior counselor to the president, Kellyanne Conway; Director of Communications Omarosa Manigault; Deputy National Security Advisor Kathleen McFarland, among others.

According to a report by the Independent, the White House chief calligrapher Pat Blair, who designs all the official documents, including formal invitations on behalf of the president, takes home $102,212. The report also adds that his subordinates Debra Brown and Becky Larimer earn $90,828 and $70,100, respectively, a year.

Although the president has never spoken about equal pay, his daughter Ivanka on April 4 on Equal Pay Day posted a tweet stating women too deserved equal pay at work.

She also took to Instagram to voice her opinion on the matter. “Closing the gender pay gap is critical to the economic empowerment of American women, and it is the responsibility of all Americans to come together in pursuit of equal pay. I am proud to work toward this goal alongside my father and in support of the administration’s commitment to women and families,” she wrote, and posted a graphic, detailing the disparities in gender pay.

It is not just the White House where there is a gender gap in pay. The technology sector, too, has seen a considerable gap in the salaries of men and women employees. According to a study conducted by San Francisco-based career marketplace site Hired, women in tech earn less than their male counterparts 63 percent of the time in 2017, down from 69 percent the previous year. Female tech workers received, on average, pay offers that were 4 percent lower than those of male hires.

The issue has been flagged in Hollywood, too, with several actors speaking against the gap. While promoting her films "The Jungle Book" and "Captain America: Civil War," actor Scarlett Johansson told Cosmopolitan, "I think every woman has [been underpaid], but unless I’m addressing it as a larger problem, for me to talk about my own personal experience with it feels a little obnoxious,” she said adding, “It’s part of a larger conversation about feminism in general.”
