World Christian Database

Updated to 2010

The core religious data of the World Christian Database has been updated from mid-2005 to mid-2010.

This means that estimates for the number of religionists in every country of the world are now reconciled with the United Nations population projections for mid-2010. The update includes statistics on all world religions as well as the peoples (first round of projections), cities, provinces and country tables.

Unless labelled otherwise, all data in WCD now refer to 2010 and this update includes two new data points (1950 and 2010) which have been added to the religious change over time tables for all countries.

Note that Christian denominations and communions remain labelled as AD 2005 until the next quarterly update in April when the first estimates for 2010 denominations will be added, along with a second round of reconcilliation of 2010 data in the Peoples table.

Included in this update are new projections of religious adherents for 2025 and 2050.
