Tajik is the official language of Tajikistan. 80% of the population of this country is Tajik so Tajik language is the most influential language in the country. People in the Badakhshan region of the southeastern part of the country speak Tajik as well as Pamiri. In addition to Tajikistan, the people of Samarkand and Bukhara, two very important cities in Uzbekistan, speak Tajik. Uzbekistan's official statistics show that 5% of the population is Tajik. Of course, this does not include many Tajiks. They identify themselves as Uzbeks. The "Uzbekization" system, led by Sharaf Rashidov, head of the Communist Party of Uzbekistan during the Soviet era, requires Tajiks to adopt two approaches - to live in Uzbekistan as Uzbek, or to move to a backward and mountainous region (now Tajikistan). This "Uzbekization" process ended in 1924. It is estimated that Tajiks currently represent 25-30% of the total population of Uzbekistan. In southern Afghanistan, 25 to 30 percent of the population is Tajik. The Tajik language they speak is called Dari. In addition, in many parts of Central Asia, such as Kazakhstan and Russia , there are many Tajik-speaking people. Due to the economic downturn in Tajikistan, an estimated one million Tajiks migrate to Russia each year to earn a living.
