List of cities in Afghanistan
The only city in Afghanistan with over 1 million population is its capital, Kabul. The rest are smaller cities and towns. According to the CIA, an estimated total number of people living inside Afghanistan was 31,822,848. Of this, around 6 million or so were reported to be living in urban areas and the rest in rural or countryside.
History of Afghanistan (1978–92)
As the Afghan–Soviet war became more destructive, internal refugees flocked to Kabul and the largest of the provincial cities. Varying estimates (no authentic census was taken) put Kabul's population at more than 2 million by the late 1980s. In many instances villagers fled to Kabul and other towns to join family or lineage groups already established there.
