There are also the differing enrollment rates between boys and girls. UNICEF found that in 2013–2014, enrollment numbers for boys was at about five million while girls were at about 4.2 million. While the out-of-school rate for girls is at about 11%, boys are at less than half of that. There is still a gap between boys and girls in terms of educational opportunities. However, the rate of enrollments for girls has been increasing at a higher rate than for boys. In 2015–2016, the enrollment numbers for girls increased by 400,000 from the previous year where a large number of them were located in Iraq Centre. Not only that, UNICEF found that the increase of girls going to school was across all levels of education. Therefore, the unequal enrollment numbers between boys and girls could potentially change so that universal education can be achieved by all at equal rates.
