Large areas of land are part of the Sahara Desert and are sparsely inhabited. The majority of Egyptians today are urban, living in the great Arab population centers of greater Cairo, the largest city in Africa, and Alexandria.

Desert wiki:
eography">geography, a desert is a landscape form or region that receives little precipitation - less than 250 mm per year. Deserts have a reputation for supporting very little life. Compared to wetter regions this may be true, although upon closer examination, deserts often harbor a wealth of life that usually remains hidden (especially during the daylight) to preserve moisture. Approximately one-third of Earth's land surface is desert. (See a map of the world's non-polar deserts, http://pubs.usgs.gov/gip/deserts/what/world.html.)
