Afghanistan
The population of Afghanistan was estimated at 29.2 million in 2017. Of this, 15 million are males and 14.2 million females. About 22% of them are urbanite and the remaining 78% live in rural areas. 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. This makes the total Afghan population at around 33,332,025, and its current growth rate is 2.34%. This population is expected to reach 82 million by 2050 if current population trends continue.
War in Afghanistan (1978–present)
In 2001 alone, according to several international sources, 28,000–30,000 Pakistani nationals, 14,000–15,000 Afghan Taliban and 2,000–3,000 Al Qaeda militants were fighting against anti-Taliban forces in Afghanistan as a roughly 45,000-strong military force. Pakistani President Pervez Musharraf – then as Chief of Army Staff – was responsible for sending thousands of Pakistanis to fight alongside the Taliban and Bin Laden against the forces of Ahmad Shah Massoud. Of the estimated 28,000 Pakistani nationals fighting in Afghanistan, 8,000 were militants recruited in madrassas filling regular Taliban ranks. A 1998 document by the U.S. State Department confirms that "20–40 percent of [regular] Taliban soldiers are Pakistani." The document further states that the parents of those Pakistani nationals "know nothing regarding their child's military involvement with the Taliban until their bodies are brought back to Pakistan." According to the U.S. State Department report and reports by Human Rights Watch, the other Pakistani nationals fighting in Afghanistan were regular Pakistani soldiers especially from the Frontier Corps but also from the Pakistani Army providing direct combat support.
