This is closely connected, in many relatively socially conservative contexts, with the need to ensure (the prerequisite of) marriage. The World Bank estimates that one year of female schooling reduces fertility by 10 percent, particularly where secondary schooling is undertaken. Not only that, but as indicated earlier, these women are less likely to undergo early pregnancy. Being better informed increases the chances of women knowing how to space their pregnancies better, how to access pre and post-natal care, including prevention of HIV/AIDS, sexually transmitted diseases and family planning in general. The World Bank estimates that an additional year of schooling for 1,000 women helps prevent two maternal deaths. An educated mother is more likely, it is maintained, to attempt to ensure educational opportunities for her children.
