Christianity is now a majority-global South religion, with more believers living in Africa, Asia, and Latin America than in Europe and North America. However, most Americans have little exposure to Christians around the world. Global Christianity: A Guide to the World’s Largest Religion (Zondervan, 2022) is an accessible reference work to help readers understand changes in Christianity in every country of the world with maps, charts, and short narratives.
The World Christian Encyclopedia is the authoritative reference work on global Christianity, now in its third edition (Edinburgh University Press, 2019). Its oversized 1,000 pages includes detailed information on religious adherents, Christian denominations, and history of Christianity in every country of the world. The Encyclopedia is available in hardback (paperback forthcoming from Hendrickson Publishers) as well as PDFs.
The full-color 32-page Global Overview is available for download for only $20!
The World Christian Database and World Religion Database, both published by Brill, contain detailed quantitative information on Christianity and other world religions in every country of the world, with estimates for the past, present, and future.
