Kabul is a city located in Afghanistan. It is the capital city, as well as the largest city by population. Not only is it the largest city in the country, but it also one of the largest in the world, ranking 64th. Rapid urbanization has also led to the city being the fifth fastest-growing in the world.

The city is spread across a total of 1,023 square kilometers (395 square miles) and has a population density of 4,500 residents per square kilometer (12,000 per square mile).
About 45% of Kabul’s population is Tajik. One-quarter is Hazara, another 25% is Pashtun, and minority ethnic groups include Baloch, Uzbek, Turkmen, and Afghan Hindu.

The common language is Dari, although Pashto is widely spoken throughout the city as well. Many inhabitants speak more than one language.
The city’s population has seen very exciting changes throughout the years, primarily due to wars. The population dropped in the 1990s but has grown four times between 2001 and 2014, as immigrants move away from rebel groups and government forces. The city is now one of the fastest-growing in the entire world, and because of this, many informal settlements have popped up all around the city to accommodate this growth. The city’s population in the past has fluctuated throughout the years; however, its current trajectory hasn’t shown signs of slowing just yet.
