Egypt (Arabic: مصر Misr ;), officially the Arab Republic of Egypt, is a country in North Africa that includes the Sinai Peninsula, a land bridge to Asia. Covering an area of about 1,001,450 square kilometers (386,560 square miles), Egypt borders Libya to the west, Sudan to the south, and Palestine and Israel to the northeast; on the north and the east are the Mediterranean Sea and the Red Sea, respectively.
Egypt is the fifteenth most populous country in the world. The vast majority of its 78.8 million people (2006) live near the banks of the Nile River (about 40,000 km² or 15,450 sq miles) where the only arable agricultural land is found. Large areas of land form part of the Sahara Desert and are sparsely inhabited. Around half of Egypt's residents live in urban areas, with the majority spread across the densely populated centers of greater Cairo (the largest city in Africa and the Middle East), Alexandria and other major towns in the Nile Delta.
