Mobile has the power to transform lives. It can empower women by making them feel safer and more connected, and provide access to information, services and life-enhancing opportunities like health information, financial services and employment opportunities, often for the first time. However, in today’s increasingly connected world, women are being left behind. This report intends to draw attention to women’s unequal access to mobile technology and to spur action on this important issue. The analysis, which is based on findings from quantitative face-to-face surveys with women and men in 23 low- and middle-income countries across Asia, Africa and Latin America, provides evidence of the persistence and scale of the mobile gender gap across low- and middle-income countries, including the barriers that women and men face to owning mobile phones and using mobile internet.
