McKinsey Global Institute's Gender Parity Score (1.00 = gender parity)
Research from a recent McKinsey & Co. post,
Globally, women spend thrice the amount of time as men on unpaid care work—an economic contribution conservatively worth $10 trillion, or 13 percent of global GDP, for which they are not compensated or recognized. Turning to work that is paid and measured, women generate about 37 percent of the world’s GDP, despite being about half of the world’s total population. At current rates of progress in women rising to the C-suite, it will take more than 100 years to bridge the gender gap in the upper reaches of US corporations.
