World Religion Database


The World Religion Database (WRD) contains detailed statistics on religious affiliation for every country of the world. It provides source material, including censuses and surveys, as well as best estimates for every religion to offer a definitive picture of international religious demography.

It offers best estimates at multiple dates for each of the world’s religions for the period 1900 to 2050. The WRD will be constantly updated with new sources of data as they become available, such as estimates of religious affiliation at the province level within countries and religious freedom information for all countries.
