Todd M. Johnson is Associate Professor of Global Christianity and Director of the Center for the Study of Global Christianity at Gordon-Conwell Theological Seminary in Boston, MA. Johnson is visiting Research Fellow at Boston University’s Institute for Culture, Religion and World Affairs leading a research project on international religious demography. He has published encyclopedias, atlases, databases, monographs, and scholarly articles on counting religionists around the world. In particular he has made detailed country-by-country estimates for ethno-linguistic peoples, religious diversity, Pentecostals, Sunnis and Shia’s, and other traditions within the world’s major religions.

Todd Johnson was born in St. Paul, Minnesota but has spent several years in Singapore and Thailand. Todd is married to Tricia (1983) and has three daughters, Laura (1988), Claire (1991), and Valerie (1998). As a family they take pleasure in bike riding, hiking, and international food. Todd enjoys haunting used bookstores, collecting music and film from around the world, and cross-country skiing in the winter. For the past 30 years, he has daily mined Christian history and global Christianity for insights into his own faith journey.
