List of countries by Zoroastrian population

List of countries by Zoroastrian population is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand List of countries by Zoroastrian population rather than just read about it. In short: 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.

Reference excerpt

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. These numbers indicated a notable population decline in comparison with the earlier projection of 124,953 people. Besides Iran and India, Zoroastrians are found in Pakistan, Afghanistan, China, Bangladesh, Kazakhstan, Tajikistan, Sri Lanka, Uzbekistan, the United States, the United Kingdom and Canada. The larger part of the Zoroastrian population consists of the Parsis, a community standing at around 50,000 people in India according to the 2011 census and around 2,348 Parsis in Pakistan according to the 2023 census. In 1994, the Zoroastrian Society of Ontario estimated that there were around 100–200 Zoroastrians residing in Afghanistan. In 2015, the Kurdistan Region of Iraq (KRI) granted official recognition to the Zoroastrian religion and also proceeded with the opening of three new Zoroastrian temples. The KRI's Zoroastrian community has claimed that thousands of people residing in the autonomous territory have recently converted to Zoroastrianism from Islam. In 2020, a KRI-based Zoroastrian advocacy group known as the Yasna Association, which also functions as a representative of the faith within the KRI's government, claimed that about 15,000 people had been registered with the organization as of 2014. However, 2024 estimates showed a smaller figure of nearly 5,000 living in the region, primarily in Sulaymaniah Governorate. A 2020 social media-based survey by GAMAAN found a much larger percentage of Iranians identifying as Zoroastrians at 7.7% while two 2022 surveys from GAMAAN found 1% to 5% identifying as Zoroastrian. The survey is however questionable as it used self-selecting participants, reached through social media and chain referrals. According to Iran’s 1996 census, the Zoroastrian population stood at nearly 28,000. By 2006, it had dropped to 19,823. The 2016 census recorded 23,109 Zoroastrians in Iran. The Federation of Zoroastrian Associations of North America put the number of Zoroastrians in Iran at up to 25,271 in 2012, equivalent to 0.03% of an 87.6 million population. There are no official numbers for the Zoroastrian population in the US. The World Zoroastrian Federation estimates the number between 10,000 and 15,000, while the North American Zoroastrian Association puts it closer to 20,000, including both Iranian Zoroastrians and Indian Parsis.

Worked examples

Example 1 — a first encounter with List of countries by Zoroastrian population

Start with the simplest possible case. Write down what List of countries by Zoroastrian population claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to List of countries by Zoroastrian population before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about List of countries by Zoroastrian population ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of List of countries by Zoroastrian population

In research: List of countries by Zoroastrian population appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses List of countries by Zoroastrian population in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: List of countries by Zoroastrian population is common in secondary-school and first-year university syllabi. It links to neighbouring topics Lists of countries, Zoroastrianism-related lists, so understanding it makes those chapters shorter.
In everyday life: Look for List of countries by Zoroastrian population outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
