  6. Does female schooling reduce fertility? Evidence from Nigeria In summary, our results provide robust evidence that female education reduces the number of early births.

  12. HIV/AIDS thrives in poverty. Fig 35.4

  13. Those most affected by an epidemic are precisely those who are affected by that environment. In the case of HIV/AIDS in Africa, these are adolescent girls and young women, especially in urban areas.

  14. prevalence rates for girls are generally higher than boys

  15. At the age of 12, except for those infected through parent to child transmission (and sexual abuse), almost no adolescent girls are HIV+. Six years later, in high-prevalence countries, 10–20 per cent are infected.

  16. Among unmarried girls aged 10–19 in two low-income areas in Addis Ababa,(38) it was found that: • 13 per cent felt they had a place to meet safely with friends (compared to 47 per cent of boys) • 32.1 per cent had had sex at times they did not want to; • the first experience of sex for 24.8 per cent of the girls was forced • 14 per cent said that they had been raped.

  17. In Ethiopia, young domestic workers (girls aged 10–14 who constituted 12 per cent of the adolescent population in the same areas) worked, on average, 62 hours a week for less than US$ 8 a month. 96% of them had migrated (or been migrated) to Addis Ababa.

  18. Africans are not being infected in such numbers because they are more sexually promiscuous. UNAIDS statistics show that more Americans than Africans start having sexual relations at an early age, and America and Britain have some of the highest teenage pregnancy rates in the world… but still lower than in Sub-saharan Africa.

  19. Only 3 per cent of female contacts were married, despite the fact that the vast majority of girls in Ethiopia get married during adolescence, and the vast majority of girls’ sexual activity during adolescence takes place in the context of marriage (94 per cent).

  20. One remedy for such a dismal situation is ensuring that girls have access to education. UNICEF, the World Bank and others have argued that education is a “social vaccine”, the only vaccine available to inoculate children and young people against HIV/AIDS. Ratio of girls : boys in primary and secondary school (2000)
