Tajiks are the dominant ethnic group in Northern Afghanistan as well, and are also the majority group in scattered pockets elsewhere in the country, particularly urban areas such as Kabul, Mazar-i-Sharif, Kunduz, Ghazni and Herat.
Tajiks constitute between 25% and 30% of the total population of the country.
Tajik also retains numerous archaic elements in its vocabulary, pronunciation, and grammar that have been lost elsewhere in the Persophone world, in part due to its relative isolation in the mountains of Central Asia.
Tajiks are also found in large numbers in the Surxondaryo Region in the south and along Uzbekistan's eastern border with Tajikistan.
The dialect used by the Bukharan Jews of Central Asia are known as the Bukhori dialect and belong to the northern dialect grouping.
Approximately 15-30% of Afghan citizens are native speakers of Dari.The table below lists the six vowel phonemes in standard, literary Tajik.Letters from the Tajik Cyrillic alphabet are given first, followed by IPA transcription.Tajik is still widely spoken in Samarqand and Buxoro today, as Tajiks account for perhaps 70% of the total population of Samarqand and have been estimated to make up as much as 90% of Buxoro.During the Soviet "Uzbekisation" supervised by Sharof Rashidov, the head of the Uzbek Communist Party, Tajiks had to choose either to stay in Uzbekistan and get registered as Uzbek in their passports or leave the republic for the less-developed agricultural and mountainous Tajikistan.
A large Tajik-speaking diaspora exists due to the instability that has plagued Central Asia in recent years, with significant numbers of Tajiks found in Russia, Kazakhstan, and beyond.
