*Folk religions include followers of African traditional religions, Chinese folk religions, Native American religions and Australian aboriginal religions.
**The “other religions” category includes Bahai’s, Jains, Sikhs, Shintoists, Taoists, followers of Tenrikyo, Wiccans, Zoroastrians and many other faiths. Population estimates of 9,999 persons or less are identified as “<10,000.” All other counts are rounded to the nearest 10,000. Percentages are calculated from unrounded numbers. Figures may not add exactly due to rounding. Estimated 2010 total population figures are based primarily on the 2010 revision of the United Nations World Population Prospects data. The United Nations provided the Pew Forum with special estimates for Sudan and the new nation of South Sudan. The population estimate for Kosovo is based on the figure from the World Religion Database, which is deducted from the U.N.’s Serbia estimate.
