Demographic Trends in Middle Eastern Christianity: Past, Present, and Future

Abstract

One of the most profound changes in the global religious landscape in recent history has been the proportional decline of long-standing Christian communities in the Middle East. Christians represented 12.7 percent of the Middle East’s population in 1900 but only 4.2 percent in 2025; by 2075 they will likely constitute 4.1 percent of the region. Yet, while Christians are leaving the Middle East in large numbers, many oil-rich countries have experienced an influx of expatriate Christian workers from around the world, making the religious demographic situation of the Middle East quite unique. This article describes the dynamics of Christian growth and decline in the context of global Christian trends from 1900 to 2025. In doing so, it highlights the unique ecclesiastical contexts of Middle Eastern Christians and draws connections among Christianity, migration, and gender. It concludes with reflections on the Middle Eastern diaspora considering the shape of World Christianity in the twenty-first century.
