It is often asked "How many lived in Jerusalem during the time of Jesus?"
But there is really no reliable sources that would indicate any population figures during the time of Jesus. The main sources available estimate a population of around 80,000 to 100,000 citizens. But hundreds of thousands of Jews from the Diaspora which numbered around 4,000,000 visited Jerusalem for the Passover and other festivals yearly with an estimated 3,000,000 people, both Jews and Gentiles, visiting Jerusalem during the Passover when the Lamb of God was lifted on a Roman cross.
