World Christian Database

Church membership

Most countries have had a significant strengthening of their 2005 church membership data, as published reports increasingly become available to replace projections from earlier years.

It is a fact of research life that statistics are usually required for 'the present' but there is a significant time lag between when statistics are gathered and when they can be published. Census data, for example, often takes several years from the time of the data collection to the time of first publication. In the meantime, population estimates are made by projecting data from previous years.

The World Christian Database is now in the final stages of consolidating global denominational membership with published membership data for the year 2005. This, together with it's earlier consolidated position for the year 2000, will provide a solid basis for projection to 2010 which in time will become WCD's next 'base year'.
