Religion Research & Data

Explore data, surveys and research about religious affiliation, demographics, religious change and belief around the world.

Our goal is to make reliable research easier to understand while preserving the context needed to interpret statistics responsibly. Every figure we publish identifies its original source, the year it was collected and the population it describes.

Our current research focus is religious demographics country by country, drawing on national censuses and statistical agencies (such as Singapore's SingStat, Malaysia's DOSM, Australia's ABS and the UK's ONS) and major research organisations (such as Pew Research Center). The completed country studies below each include original data tables and charts.
