Which religious group is geographically more widespread, Baha'i or Jehovah's Witnesses?
Has it always been that way? If not, when did it change, and why?
GT, thank you for your answer, and the links. I have heard it said of well-traveled Christians and other non-Baha'is that stated they found Baha'i communities already well established in places "where Christianity has scarcely been heard of." And what with the Baha'i Faith being persecuted and even legally banned, there are Baha'is living in more lands than what is officially stated.
As much as Jehovah's Witnesses voice how they are "persecuted" they never even approach what Baha'is have and still are enduring. Anecdotal perhaps, but I believe the Baha'i Faith may already be the world's most widespread.
J, to add to what you offered:
"The Baha'i Faith is the only religion to have grown faster in every United Nations region over the past 100 years than the general population; Baha’i was thus the fastest-growing religion between 1910 and 2010, growing at least twice as fast as the population of almost every UN region."
