The community that carries the Zoroastrian tradition today is small in number but widely dispersed. Most careful estimates place the global Zoroastrian population at roughly 100,000–120,000 adherents, with some surveys allowing a somewhat wider range. Despite this numerical modesty, the tradition persists as a distinct and recognizable spiritual lineage, sustained by tightly knit communities and a strong sense of inherited identity.

The largest concentration is found in India, especially among the Parsis of Mumbai and Gujarat, who form a substantial portion of the global community. Iran, the ancestral homeland of the faith, still maintains a significant Zoroastrian presence, particularly in urban centers and historic regions associated with the tradition. Beyond these heartlands, notable communities have taken root in North America and the United Kingdom, where migration has carried the faith into new cultural settings.

Smaller Zoroastrian groups are also present in Pakistan and in various parts of the wider diaspora. These include communities in Australia, New Zealand, the Persian Gulf states, and several European countries, where numbers are modest but the religious identity remains consciously preserved. Taken together, these scattered yet interconnected communities show how an ancient monotheistic tradition continues to live on, not through large numbers, but through continuity of practice, memory, and shared spiritual heritage.
