Updates

This quarter sees data released from a further 22 censuses and 36 surveys conducted mainly in Europe and from a variety of sources. Years of study range from 1995 (a Parliamentary Election survey in Belarus) to 2010 (Register of Religious Communities in Finland). A full listing of the new survey data is available in the query "Survey data added this quarter" on the Censuses and Surveys page.

The base year of WRD has been moved from mid-2010 to current projections for mid-2015. Estimates for the number of religionists in every country of the world are now reconciled with the United Nations population projections for mid-2015. The update includes statistics on all world Religions as well Peoples and Countries, with preliminary data on Cities and Provinces.
Also this quarter the WRD Methodology document has been revised to include material from Todd M. Johnson and Brian J. Grim, The World’s Religions in Figures: An Introduction to International Religious Demography (Oxford: Wiley-­-Blackwell, 2013)
