ONE VIEW: Iran has no freedom of religion and Islam forbids the open conversion of its followers to other faiths under pain of death, although many out conversions of Islam are done clandestinely.
Religions such as Yaresan and Mandeism are not officially recognized, neither are Hinduism and Buddhism. The government statistics are highly unreliable and obvious propaganda as many Iranians born Muslim no longer practice that faith although they are still counted as "Muslim".
In 2007, a survey of some 4,000-5,000 young people was conducted, free from government interference, politics and persecution. The results are the following
(Approximately 3 out of 4 participants were male)
1) Islam--> 62% among males; 76.8% in females (definitely not 98% advertised by IRI)
2) No religion--> 30.7% in males; 14.9% in females
3) Bahaism --> 3% in males; 3.4% in females
4) Zoroastrianism --> 2.5% in males; 1.8% in females
5) Christianity --> 0.3% in males; 1% in females
6) Judaism --> 0.1% in males; 0.3% in females
7) Other (Yarsanism, Mandeism, Hinduism, Buddhism) -->0.7% in males; 1.3% in females
8) No answer --> 0.7% in males; 0.5% in females
ANOTHER VIEW:
It is indeed considered illegal for a Muslim to convert to another religion in Iran. However, Iran does recognize the Islamic concept of Ahl al-Kitab, or "People of the Book". This provides Christians and Jews (and Zoroastrians, in Shiite Islam) "sanctuary", essentially, due to the Islamic concept that the Torah and The Bible have been corrupted but in the end the people of these religions are worshipping the same God as Muslims in good faith. Each of these three minor religions have a guaranteed seat in the Majles (Parliament) and is allowed to worship as they please, although they cannot hold government office other than the aforementioned Majles seat. The statistics cited above may very well be correct, but take it with a grain of salt as surveys in Iran are generally considered unreliable. In addition, understand that "Islam" is combining both Shiites and Sunnis together - about 20-30% of the Muslims in Iran are Sunni Muslims, while the state religion is Shia Islam.
The majority religion in Iran is Shi'ite Islam.
Shi'aa.The majority or 90% of all Muslims in Iran are Shiites. Shi'a Islam is the official state religion of Iran. Sunni and Sufi only represent 9%of the Muslims there.

Both. Shiites are primarily concentrated in Iran and the southeast of Iraq. In both countries, they constitute a majority of the country's inhabitants, although Iran's majority is larger both in number and percentage,
The dominant religion of Iran is Islam (majority Shi'ite), while the Baha'i Faith is the largest non-Muslim minority religion.
The Bahá'í Faith has its origins in Persia (now called Iran); the majority religion there is Shia Islam. However, the first official proclamation (the founder, Bahá'u'lláh, formally stated that he was the Messenger of God expected according to previous prophecies) was in Baghdad, which was then part of the Ottoman (Turkish) empire. The majority religion there is Sunna Islam.
The majority of Iranians follow Shi'ite Islam.

No country has a Zoroastrian majority. There are minorities in many countries, notably India, Iran and Pakistan.
"Iranian" is a nationality (those from the country of Iran). The majority of Iranians are Shi'ite Muslims.
No. Farsi is a language, also called Persian. Farsi is similar in sound and writing to Arabic, and is spoken mainly in Iran, Afghanistan and Tajikistan.
The Bahá'í Faith was greatly affected. There has been, and still is, a large-scale persecution against the Bahá'ís, which is the largest majority in Iran.
