populations pie chart statistics list
This pie chart is based on statistics listing peoples self-admitted adherence to one of the major world religions, or to other faiths, or
to people stating that they are of no religion.
Christians: 2,100,000,000 - tending to decline in terms of global percentage
As you will see the pie chart only mentions percentages of the world's population whose religiously related self-admission places them in each category.
To get a better idea of the numerical population size statistics please consult the following list of the major world religions.
Muslims: 1,500,000,000 - tending to increase in terms of global percentage
Of no religion: 1,100,000,000 - tending to decline in terms of global percentage
Hindus: 900,000,000 - stable in terms of global percentage
Chinese folk religionists: 400,000,000
Primal religionists: 400,000,000
Buddhists: 375,000,000- stable in terms of global percentage
This listing of figures hopefully gives a good approximation of the world's populations self-professed adherence to major world religions,
other religions, or their self-professed state of not being religious.

The Muslim, Hindu, Buddhist and Jewish faiths all feature differences
of faith interpretation, outlook, or practice, which are or similar significance
to the Catholic, Protestant, Orthodox and Other divergences within Christianity.
Trends in adherence to the major World Religions are probably linked to differing rates by which populations
are changing in the World's various regions of "prevailing historical religious beliefs" or of the "marked onset of secularism".
