Our world is increasingly unequal. But this inequality is not only about money. It’s also about power, rights and opportunities. And it has many dimensions that feed on each other. One dimension of inequality that has received too little attention is in the enjoyment or denial of reproductive rights and the effects of that on half of humanity. This is the focus of the UNFPA flagship report, The State of World Population 2017 - Worlds Apart - is a clarion call for putting power in the hands of women to control their reproductive choices and their futures. With that power in women’s hands, Worlds Apart no longer holds. With that power, instead of separation and inequality, fairness prevails--and a more equitable world for women and girls is the reward.
