Egypt’s current government, a semi-presidential republic led by president Abdel Fattah el-Sisi since he was elected in 2014, has been described by a number of watchdogs as authoritarian and responsible for perpetuating the country’s poor human rights record. Islam is the official religion of Egypt, and Arabic is its official language. The great majority of its people live near the banks of the Nile River, an area of about 40,000 square kilometres (15,000 sq mi), where the only arable land is found. The large regions of the Sahara desert, which constitute most of Egypt’s territory, are sparsely inhabited. About 43% of Egypt’s residents live across the country’s urban areas, with most spread across the densely populated centres of greater Cairo, Alexandria and other major cities in the Nile Delta.
