I want to know the answer to the following question:
What percentage of Iran speaks any type of Iranian language?
All the background I'm provided with is that "The CIA's World Factbook has estimated that around 79% of the population of Iran are a diverse Indo-European ethno-linguistic group that comprise the speakers of Iranian languages, with Persians constituting 53% of the population, Gilaks and Mazanderanis 7%, Kurds 10%, Lurs 6%, and Balochs 2%.". Is that enough to answer the question?
Answer: yes
