About 90 percent of Egyptians are Muslim, which means they are followers of the Islamic religion. About 10 percent of Egyptians are Copts, one of the oldest branches of the Christian religion. Egypt’s population is growing rapidly. This puts strains on Egypt’s resources, since most people live in a narrow strip of land along the Nile River. Having so many people in such a small area can cause overcrowding, from schools to apartment buildings to hospitals. Children are highly valued in Egypt, especially in rural areas where they help on family farms. Children are also expected to look after their parents in their old age.
