Q: I keep hearing different estimates being cited about how many Christians there are in Egypt. What are the facts?
A: The numbers are debated. Media reports, sometimes citing officials of the Coptic Orthodox Church, frequently say that Christians make up 10% or more of the country's approximately 80 million people. But researchers at the Pew Forum on Religion & Public Life have been unable to find any Egyptian census or large-scale survey that substantiates such claims.
