Interpretation
Regional Distribution Interpretation
The world's religious map shows a clear case of divine real estate, where faiths have staked their claims with astonishing precision—from Christianity and Islam dividing Africa like an old treaty, to Hinduism and Buddhism holding an almost exclusive Asian-Pacific timeshare, and even tiny Zoroastrianism keeping a tenacious foothold in its historic homes—proving that while doctrines may be universal, their addresses are decidedly local.
