This article represents the results of analysis of data on religion for all of the countries of the world which appear in the World Religion Database (Johnson and Grim 2023). Data was collected at the national level from a number of sources including censuses, surveys, polls, religious communities, scholars, and others. After data collection and analysis, discrepancies were worked out and best estimates are made for each religion across a number of years. Results are presented for religionists and non-religionists as a whole as well as for each religious and non-religious category. [ABSTRACT FROM AUTHOR]

To supplement our global assessment of 18 religions in a previous article in this issue of the journal, here we offer analysis of religious affiliation by the globe and six continents: Africa, Asia, Europe, Latin America, Northern America, and Oceania. Estimates of religious affiliation are made for four dates, 1970, 2000, 2023, and projections for 2030. We also contrast growth in two 30-year periods, 1970–2000 and 2000–2030. These global and continental tables are based on country data (World Religion Database). United Nations regional tables (e.g., Western Africa) can also be constructed from the country data.
