Karachi

Karachi is the biggest metropolis in Pakistan and the twelfth-largest city in the world, with a population of over 12 million people. It serves as the administrative centre of the Pakistani province of Sindh. It is Pakistan's main industrial and financial centre, and its GDP (in purchasing power parity) is projected to be $164 billion (PPP) as of 2019. It is ranked as a beta-global city by the World Economic Forum. Karachi is Pakistan's most cosmopolitan metropolis, with a linguistic, cultural, and religious diversity that is unparalleled in the country. It is also one of the country's most secular and socially liberal cities. Because of its position on the Arabian Sea, Karachi acts as a transportation centre, and it is home to Pakistan's two biggest seaports, the Port of Karachi and Port Bin Qasim, and also Pakistan's busiest airport, the Jinnah Airport Terminal. Karachi is also the capital of Pakistan.

The city of Karachi, formerly known as the "City of Lights" for its lively nightlife in the 1960s and 1970s, was wracked by ethnic, sectarian, and political strife in the 1980s, after the large-scale introduction of weapons during the Soviet–Afghan War. In recent years, the city has gained a reputation for having high rates of violent crime, although the number of reported crimes has dropped dramatically as the result of a crackdown operation launched in 2013 by the Pakistan Rangers against criminals, the MQM political organisation, and Islamist militants. In the wake of the operation, Karachi's ranking as the world's sixth most dangerous city for crime fell to 115th place by the middle of 2021, down from sixth in 2014.
