World Religion Database

International Religious Demographic Statistics and Sources

The World Religion Database (WRD) contains detailed statistics on religious affiliation for every country of the world. It provides information from country censuses as well as best estimates for every religion to offer a definitive picture of religion and non-religion in the past, present, and future.
It offers best estimates at multiple dates for each of the world's religions for the period 1900 to 2050. The WRD is regularly updated with new sources of data, such as estimates of religious affiliation at the province level within countries and religious freedom information for all countries.

'The World Religion Database marks an important step for the study of global religion. It will be an indispensable resource for scholars, journalists and anyone else interested in this increasingly salient phenomenon.'
Peter L. Berger, Boston University

'Whether as a researcher or as an interested citizen, it is enormously important to have good data on the shape of religion in today's world. This new resource makes that information reliable and accessible.'
Nancy T. Ammerman, Boston University

'Religion is constantly in the news. Effective contributions to these frequently crucial debates require accurate sources of data. The World Religion Database is one such – I recommend it very strongly.'
Grace Davie, University of Exeter

'The World Christian Database is the most valuable and authoritative source for demographic data on Christian bodies available on the Internet (or elsewhere). The new World Religion Database is destined to extend that valuable service to the entire range of the world’s religious groupings. I recommend it highly to all researchers in religious studies.'
