List of countries by Zoroastrian population

In 2012, a study by the Federation of Zoroastrian Associations of North America (FEZANA) published a demographic picture of Zoroastrianism around the world, in comparison with an earlier study from 2004. The study projected a global Zoroastrian population of 111,691–121,962 people, with roughly half of this figure residing in just two countries: India and Iran.
