Kabul Province 

It is not possible for 60% of Kabul to be Pashto-speakers. That number makes no sense. The government of Afghanistan is not as reliable as outside sources since it is currently dominated by Pashtuns. In all scholarly sources Kabul city is described as a Persian-speaking city. Kabul being a Persian-speaking city alone makes the whole province Persian-speaking majority. 60% is against commons sense. Even most Pashtuns in Kabul speak Dari-Persian over Pashto.
