All you need to know about the gender pay gap - across jobs, experience, industries

It is not news that there is a income pay gap between genders at work and the gap widens as one move up to management level, according to study by Workplace Gender Equality Agency (WGEA).

PayScale's Gender Pay Gap report, took a deeper into the issue by comparing uncontrolled gender pay gap and controlled gender pay gaps.

In the US, women earn 78 cents for every dollar a man earns, according to data published by Bureau of Labor Statistics.

This pay gap, refered to as the uncontrolled gender pay gap, is calculated by comparing the average earnings of all working men to all working women.

This figure shows that there is a deep chasm between the earning power of men and the earning power of women, overall.

Women with similar qualifications working the same jobs as men are also earning less than their male peers, otherwise known as the controlled gender pay gap - at 97.3 cents for every dollar earned by a man.

After looking at more than 1.4 million salary profiles comparing men and women working the same jobs and controlling for factors such as experience, location, hours worked, education, women are earning 2.7% less than men doing the same job.

Married men with children get annual median salaries of US$67,900, while those who do not have children earn US$60,800. Single moms make US$38,200 on average yearly.

Men's salaries increase until ages 50 to 55, where they level off at an annual median salary of $75,000. Women's salaries plateau between the ages of 35 to 40 at an annual median of $49,000.

Studying more also does not seem to help women close the income gap, with the pay gap increasing with the level of education.

PhD holders have the highest controlled pay gap (5.1 %), followed by MBA holders (4.7 $), and MDs (4.6 %).
