The pressures affecting the vitality of Dari Persian today are largely economic. In order to obtain an economic advantage, speakers are giving up their traditional language for the dominant language of Iran, standard new Persian. Parents intentionally do not transmit Dari to their children in order that they may have what is felt to be an advantage in school and in life. The language loss can also occur more indirectly and less visible when people move to larger urban centers or abroad in pursuit of better economic opportunities; the lack of a complete language environment in which to immerse a child decreases or completely inhibits the transmission of the language to new generations.
