The population of Afghanistan was estimated at 32.9 million as of 2019 by the Afghanistan Statistics and Information Authority, whereas the UN estimates over 38.0 million. In 1979 the total population was reported to be about 15.5 million. About 23.9% of them are urbanite, 71.4% live in rural areas, and the remaining 4.7% are nomadic. An additional 3 million or so Afghans are temporarily housed in neighboring Pakistan and Iran, most of whom were born and raised in those two countries.
