As with the spoken languages, the ethnic group composition also remains a point of debate, mainly regarding the largest and second largest ethnic groups, the Persians and Azerbaijanis, due to the lack of Iranian state censuses based on ethnicity. 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%. Peoples of the other ethnicities in Iran make up the remaining 22%, with Azerbaijanis constituting 16%, Arabs 2%, Turkmens and Turkic tribes 2%, and others 2% (such as Armenians, Talysh, Georgians, Circassians, Assyrians).
Hafez was born in Shiraz, Iran. His parents were from Kazerun, Fars Province. Despite his profound effect on Persian life and culture and his enduring popularity and influence, few details of his life are known. Accounts of his early life rely upon traditional anecdotes. Early tazkiras (biographical sketches) mentioning Hafez are generally considered unreliable. At an early age, he memorized the Quran and was given the title of Hafez, which he later used as his pen name. The preface of his Divān, in which his early life is discussed, was written by an unknown contemporary whose name may have been Moḥammad Golandām. Two of the most highly regarded modern editions of Hafez's Divān are compiled by Moḥammad Ghazvini and Qāsem Ḡani (495 ghazals) and by Parviz Natel-Khanlari (486 ghazals).Modern scholars generally agree that Hafez was born either in 1315 or 1317.  According to an account by Jami, Hafez died in 1390. Hafez was supported by patronage from several successive local regimes: Shah Abu Ishaq, who came to power while Hafez was in his teens; Timur at the end of his life; and even the strict ruler Shah Mubariz ud-Din Muhammad (Mubariz Muzaffar). Though his work flourished most under the 27-year rule of Jalal ud-Din Shah Shuja (Shah Shuja), it is claimed Hāfez briefly fell out of favor with Shah Shuja for mocking inferior poets (Shah Shuja wrote poetry himself and may have taken the comments personally), forcing Hāfez to flee from Shiraz to Isfahan and Yazd, but no historical evidence is available. He is said to have been in Timur's court, as Hafez wrote a ghazal whose verse says if this Turk accept his homage:
Historically, the name Armenian has come to internationally designate this group of people. It was first used by neighbouring countries of ancient Armenia. The earliest attestations of the exonym Armenia date around the 6th century BC. In his trilingual Behistun Inscription dated to 517 BC, Darius I the Great of Persia refers to Urashtu (in Babylonian) as Armina (in Old Persian; Armina (    ) and Harminuya (in Elamite). In Greek, Αρμένιοι "Armenians" is attested from about the same time, perhaps the earliest reference being a fragment attributed to Hecataeus of Miletus (476 BC). Xenophon, a Greek general serving in some of the Persian expeditions, describes many aspects of Armenian village life and hospitality in around 401 BC. He relates that the people spoke a language that to his ear sounded like the language of the Persians.

Question: What percentage of the population of the nation containing Shiraz is made up of the people whose language Xenophon sounded like Armenian?
