Women that enter hospital seeking treatment for a miscarriage can be accused of attempted abortion if they are unmarried. Education has been a prime area of growth in the whole Gulf region. Primary school completion rates have grown by 15% for girls and the UAE, as well as Qatar, have the highest female-to-male ratio of university enrolments worldwide. 77% of Emirati women enrol in higher education after secondary school and make up 70% of all university graduates in the UAE. Traditionally women were encouraged to pursue female disciplines such as education and health care but this has changed recently with surges in areas such as technology and engineering. The UAE currently has four women fighter pilots and thirty trained females in the nation's special security forces. In September 2014, the UAE opened the region's first military college for women, Khawla bint Al Azwar Military School. The state-of-the-art military college provides world-class training, physical fitness sessions and leadership development. Migrants, particularly migrant workers, make up a majority (approximately 80%) of the resident population of the UAE, and account for 90% of its workforce. They generally lack rights associated with citizenship and face a variety of restrictions on their rights as workers. There are reports of undocumented Emiratis who, because of their inability to be recognized as full citizens, receive no government benefits and have no labour rights. These stateless Emiratis – also known as bidun – either migrated to the UAE before independence or were natives who failed to register as citizens. In addition, there are various incidents where local individuals have ill-treated people from overseas, just on the basis of nationality or race. Emiratis receive favorability in employment via the Emiratisation program forcing companies by law to limit the number of migrant workers in a company. This is done for the purposes of stabilizing the labor market and protecting the rights of this group as a minority in their own country. At the same time, however, due to the welfare benefits of the UAE government, many Emiratis are reluctant to take up low paying jobs especially those in the private sector; private sector employers are also generally more inclined to hire overseas temporary workers as they are cheaper and can be retrenched for various reasons, for example, if they go on strike Most UAE locals also prefer government jobs and consider private sector jobs to be below them. Migrants, mostly of South Asian origin, constitute 42.5% of the UAE's workforce and have reportedly been subject to a range of human rights abuses. Workers have sometimes arrived in debt to recruitment agents from home countries and upon arrival were made to sign a new contract in English or Arabic that pays them less than had originally been agreed, although this is illegal under UAE law.
