The World Christian database is updated twice a year, generally in January and July.

Population update
04 Jan 2008

WCD has been updated to reflect the latest population revisions from the United Nations.


The number of religionists in every country of the world are reconciled with each biennial revision of the population data produced by the United Nations population division.

This update includes the latest re-reconciliation of statistics on all Christian denominations and world religions including Peoples and Provinces.

New projections of religious adherents for 2025 and 2050 proceed from this.
