Which religion is spreading at a highest rate?

Answer 1

A:

Religion tends to grow more rapidly in impoverished countries, both because religion gives comfort and hope, and because impoverished regions tend to have higher birth rates. Christianity predominates in Europe and the Americas and therefore has a relatively low growth rate there, but continues to gain the largest number of converts in undeveloped countries and benefits from high population growth in these regions. All figures should be treated with caution, due to the difficulty of establishing the real beliefs of an individual, particularly in countries where culture or law stipulate religious affiliation.

According to Wikipedia:

• Wicca grew at an average annual growth of 143% in the United States, for the period 1990 to 2001. As Wicca is concentrated in the United States, the international growth rate is likely to be similar.
• Deism grew by a total of 717% between 1990 and 2001, although off a very small base
• Mormonism is growing at around 2.5% per annum
• Islam is growing at around 2.2% per annum
• Hinduism is growing at around 2% per annum
• Christianity is growing in excess of 1.21% per annum

Falun Gong claims a high growth rate in China, but since it is a banned religion in that country, this can not be confirmed.

Figures for absolute growth suggest that Christianity is growing at the highest absolute rate and with the largest number of converts, followed in each case by Islam.
