While women make up half of the world's working-age population, females only deliver around 37 percent of the world's current GDP and make up 40 percent of its workforce overall, MGI's "The Power of Parity" report suggests.
Data and issues related vary depending on region. In developed societies like the U.S., the gap is narrower, with 46 to 47 percent of the workforce being female and contributing as much as 41 percent of national GDP.
India however has the most to gain, with women providing only 17 percent of its national GDP. Other regions mentioned who would benefit greatly include North Africa and the Middle East (18 percent).
One key area in the report is how 75 percent of total unpaid care work (child and elderly care, cooking) is done by women. However this hard work isn't considered as traditional GDP. If it was, it could be worth $10 trillion a year.
While many reports and initiatives have urged countries towards achieving gender parity, accomplishing this goal all over still remains a challenge.
It's not just work environments that need a makeover but social environments too, whether that's increasing leadership opportunities, to changing legal protection and improving women's reach to financial and digital devices.
