A rough headcount puts the world’s Zoroastrian population at just over 100,000. Far from forming one big neighborhood, these communities are sprinkled across the globe:

• India: Home to the largest group, the Parsis clock in at around 60,000–70,000. Most are clustered in Mumbai and Pune, where fire temples still glow with the sacred dhoop of Yasna rituals.
• Iran: Once the cradle of Zoroastrianism, today’s census figures hover near 25,000. Most keep their traditions alive in Yazd and Kerman, cities where ancient towers of silence still stand sentinel.
• Pakistan: A small but resilient community of roughly 1,500–2,000, mainly in Karachi, carrying on Nowruz celebrations that weave Persian and South Asian flavors together.
• North America: The U.S. and Canada together host about 15,000 Zoroastrians—Silicon Valley Parsis mingling with new Iranian arrivals in Los Angeles or Toronto. Recent gatherings, like the Zoroastrian Trust Funds of Europe’s London symposium, underscore a lively diaspora eager to keep the faith’s flame burning.
• United Kingdom, Australia & Beyond: Each of these countries shelters a few thousand more adherents. London, Birmingham, Sydney and Melbourne boast small fire temples where English, Gujarati and Farsi mix in conversation. Even pockets in the UAE and Europe keep the rituals—and the community spirit—alive.

Declining birth rates and an aging profile have made this a tight-knit tribe, with many cultural initiatives on the boil to welcome younger generations. Whether in the heart of old Persia or spread across cityscapes half a world away, today’s Zoroastrians prove that ancient faiths can still light up modern lives.
