The population of the Cairo metropolitan area has increased from less than 6 million in 1965 when the first picture was taken, to more than 10 million in 1998 (United Nations Population Division, World Urbanization Prospects, the 1999 revision). Population densities within the city are some of the highest in the world and the urban area has doubled to more than 400 square km during that period. Extraordinary rates of population growth are expected to continue, with a predicted population of around 14 million by 2015.
