‘Women hold up half the sky’ is a Chinese proverb affirming women’s equal contribution to the human experience but it is an aspirational, rather than a factual, claim. In developed and developing countries alike, gender gaps persist in education, health, work, wages and political participation. For this issue of Making It, the theme is gender equality and the economic empowerment of women. As Kofi Annan, former UN Secretary General, pointed out, “There is no tool for development more effective than the empowerment of women”. Women work two-thirds of the world’s working hours but women earn only 10% of the world’s income, and women own less than 1% of the world’s property. Women lag far behind men in access to land, credit, and decent jobs, even though a growing body of research shows that enhancing women’s economic options boosts national economies.
