Persian (Farsi and Dari) is spoken by 30 million people, in at least 26 territories. Farsi and Dari are the local names in Iran and Afghanistan respectively. The language is also closely related to Tajik. There is debate about to what extent Tajik, Farsi and Dari should be considered separate languages, or dialects of a Persian language continuum.
The majority of the population of Persian-speakers are in Iran and Afghanistan, with significant numbers also found in Pakistan, Turkey, the United States, Iraq, Canada and Saudi Arabia.
