Figure 7.4:
Major religions of the world. The world’s major religions, by numbers of adherents expressed as a percentage of world population. Note that although Judaism is a prominent religion in the United States, it does not rank among the large religions of the world in terms of total number of adherents. Also note that because some religions overlap and because of rounding, percentages do not add up to 100.
