Contained within the 4th Edition (1974) of the Atlas of Canada is a set of three maps. The first two maps show the percentage of population, by census division, who identify with a particular religion. These two maps represent the first and second statistical ranks for the most common religions. The third map shows the diversity of religion by number of dominant religious denominations as well as a breakdown of the particular religions within each census division. A supplementary graph showing the percentage of religions by province is also provided.
