From the NY Times:
After a service for the dead in which priests fed sticks of sandalwood and pinches of frankincense into a blazing urn, Mr. Antia surveyed the Zoroastrian faithful of the Midwest – about 80 people in saris, suits and blue jeans.
“We were once at least 40, 50 million — can you imagine?” said Mr. Antia, senior priest at the fire temple here in suburban Chicago. “At one point we had reached the pinnacle of glory of the Persian Empire and had a beautiful religious philosophy that governed the Persian kings.
“Where are we now? Completely wiped out,” he said. “It pains me to say, in 100 years we wonâ€™t have many Zoroastrians.”
