While most of the Millennium Development Goals face a deadline of 2015, the gender parity target was set to be achieved a full ten years earlier – an acknowledgment that equal access to education is the foundation for all other development goals. Gender disparity is defined as inequalities of some quantity attributed to the reason of gender type. In countries where resources and school facilities are lacking, and total enrollments are low, a choice must often be made in families between sending a girl or a boy to school.

In high-income countries, 95% as many girls as boys attend primary and secondary schools. However, in sub-Saharan Africa the figure is just 60%.
