The total global population ages 10–24—already the largest in history—is expected to peak in the next decade. This will have a major impact on the economic prospects for developing countries, which claim a majority of these youth. While developed countries face the challenge of providing for an aging population with fewer young people in the labor force, developing countries face a youth-heavy population bulge that will create a need for more schools and more jobs.

2. Figure 2.2 Returns to Investment in Schooling in Developing Countries by Gender Level, Page 18
By working for pay after school completion, girls reap economic benefits for themselves and their families. Economic returns to formal education in the labor market tend to be highest in lower-income countries and slightly higher for women than men.
Economic returns to education investments, in the form of eventual wages, vary by level of schooling. The returns to primary education are much higher for boys than for girls, while girls experience higher returns to secondary education investment than do boys.
Recent analyses confirm that returns to investment in education are positive and quite large in all regions of the world. The returns for girls in secondary school are particularly dramatic, and appear to have a greater positive effect on the lifetime welfare of women than does any other level of education.

3. Figure 3.6 Gender Segmentation and Wage Inequality in the Informal Sector, Page 39
Within the informal economy women are over-represented in the lowest-paid and most insecure types of employment. Since girls encounter few opportunities outside the bottom of the gender segmentation/average earnings triangle, the lower wages they receive contribute to continuation of poverty within the household, given that their income often goes to the consumption of goods and services for the well-being of household members. Young female workers are often subjected to job-related risks, including physical stress and exposure to toxins; in addition, they face risks associated with sexual vulnerability, including sexual harassment and violence.

Child marriage is much more common among poor, illiterate, and rural girls. The role of poverty in perpetuating child marriage is multifaceted. In some contexts, particularly where women have low status, child marriage is a way to reduce household poverty and relieve the financial burden girls place on their families. Child marriage is most common among the poorest 40% of the global population.

Young women’s vulnerability to HIV dominates global statistics, but the gender-specific patterns of infection show significant regional variation. In sub-Saharan Africa, the region with the largest overall number of HIV-positive young people, the number of HIV-positive young women far exceeds the number of infected young men.

Violence is part of the lives of many girls and women around the world, much of which is perpetrated by partners or family members. A population-based survey conducted in 10 countries indicated that up to half of girls ages 15–19 experienced physical or sexual violence from an intimate partner. The study showed that among women and girls who have ever been married or lived with a partner, their perpetrators are far more likely to have been an intimate partner than any other person. Unmarried and un-partnered girls are also subjected to violence, particularly sexual coercion, rape, sexual molestation in childhood, and physical abuse from family members.
