Population update

The populations of every religion in every country are freshly reconciled with each biennial revision of the population data produced by the UN: (United Nations, Department of Economic and Social Affairs, Population Division (2017). World Population Prospects: The 2017 Revision).

This WCD update provides the latest re-reconciliation of statistics on Christian denominations and world religions together with projections of all religious adherents for 2020, 2025, 2030 and 2050.

The pace of work on the forthcoming 3rd edition of the World Christian Encyclopedia (2020) continues to ramp up with collaborators from each of the 234 countries providing valuable input on Christian denominations and the state of the church in each country's context.
