Non-religious Population

Map No.


Not religious, in this sense, is everyone who is left over when you have counted adherents. The World Christian Database, on which the data is based, use the term ‘nonreligionists’ and defines it as ‘ … encompassing the 2 varieties of unbeliever: (a) agnostics or secularists or materialists, who are nonreligious but not hostile to religion, and (b) atheists or anti-religious/anti-religionists opposed or hostile to religion.

Data sources
The World Christian Database (WCD) was our main source of data for this series of religion maps compiled in 2009. Please find further information about the data and its compilation in the Worldmapper archive.

Further adjustments to the data were made in March 2018, first and foremost to account for major geopolitical changes, and adjusting to reflect the changing population distributions. We aim to map as complete data as possible and therefore estimate data for missing values. In some cases, missing data for very small territories is not used in the cartogram and that area is therefore omitted in the map.

Further notes on the data, as well as all modifications to the original data source are noted in our data sheets.
