In terms of size Cairo is not a big city. You quickly arrive at its edges in the desert or the green agricultural fields of the delta. According to official figures there are 17 million people living in greater Cairo city, a city big enough to accommodate two million. The density of people is only comparable to the Indian cities of Bombay and Delhi. Apart from that, nowhere else do so many people live so close together.
