An extra year of primary school boosts girls’ eventual wages by 10 to 20 percent. An extra year of secondary school: 15 to 25 percent. (George Psacharopoulos and Harry Anthony Patrinos, “Returns to Investment in Education: A Further Update,” Policy Research Working Paper 2881 [Washington, D.C.: World Bank, 2002].)
Research in developing countries has shown a consistent relationship between better infant and child health and higher levels of schooling among mothers. (George T. Bicego and J. Ties Boerma, “Maternal Education and Child Survival: A Comparative Study of Survey Data from 17 Countries,” Social Science and Medicine 36 (9) [May 1993]: 1207–27.)
When women and girls earn income, they reinvest 90 percent of it into their families, as compared to only 30 to 40 percent for a man. (Phil Borges, with foreword by Madeleine Albright, Women Empowered: Inspiring Change in the Emerging World [New York: Rizzoli, 2007], 13.)
