Cairo is in every respect the centre of Egypt, as it has been almost since its founding in 969 AD. The majority of the nation’s commerce is generated there, or passes through the city. The great majority of publishing houses and media outlets and nearly all film studios are there, as are half of the nation’s hospital beds and universities. This has fueled rapid construction in the city – one building in five is less than 15 years old. This astonishing growth until recently surged well ahead of city services. Homes, roads, electricity, telephone and sewer services were all suddenly in short supply. Analysts trying to grasp the magnitude of the change coined terms like “hyper-urbanization”. Cairo has the oldest and largest film and music industries in the Arab world, as well as the world’s second-oldest institution of higher learning, Al-Azhar University. Many international media, businesses, and organizations have regional headquarters in the city; the Arab League has had its headquarters in Cairo for most of its existence.
