Despite a century-long decline, religious affiliation has shown a marked resurgence globally since 1970. Both Christianity and Islam make up growing segments of the world’s population. Africa and China have witnessed the most marked religious change.
These are among the findings discussed by religious demographer Todd M. Johnson in an overview of religious identity and trends in world Christianity since 1910, presented at the Ecumenical Center here on March 13.
Hosted by the World Council of Churches (WCC) program on Ecumenical Theological Education, Johnson’s lecture preceded his participation in a WCC sponsored conference about the pedagogical uses of work from research centers on global Christianity.
Johnson is associate professor of global Christianity and director of the Center for the Study of Global Christianity (CSGC) at Gordon-Conwell Seminary in Massachusetts. He is co-author of several important resources in the emerging field of religious demography, including The World’s Religions in Figures (2013) and Atlas of Global Christianity (2009).
