Due to economic growth from oil and gas exports, Azerbaijan's quality of life and incomes have increased significantly. The government has heavily invested in international education for students as a result. Azerbaijan has a young population, over 30% of the total, and is one of the fastest growing student markets in Central Asia. The percentage of students studying abroad grew by 7.6% in 2011. The State Oil Fund of Azerbaijan has dedicated funds to support Azerbaijani students studying abroad from 2007 to 2015. According to a 2013 Azerbaijan education fair, over 5,500 students from the country attended, interested mainly in master's programs, language studies, and undergraduate degrees.
