In the present day, Cairo is heavily urbanized and most Cairenes live in apartment buildings. Because of the influx of people into the city, lone standing houses are rare, and apartment buildings accommodate for the limited space and abundance of people. Single detached houses are usually owned by the wealthy. Formal education is also seen as important, with twelve years of standard formal education. Cairenes can take a standardized test similar to the SAT to  be accepted to an institution of higher learning, but most children do not finish school and opt to pick up a trade to enter the work force. Egypt still struggles with poverty, with almost half the population living on $2 or less a day.
