Karachi capital of the province of Sindh, is the financial capital and the largest city of Pakistan. It has a metropolitan population of 11.8 million and is currently ranked 20th in the world (by population). Karachi, located on the coast of the Arabian Sea, is the financial and commercial center of the nation, as well as its largest port. The city credits its growth to the mixed populations of economic and political migrants and refugees from different national, provincial, linguistic and religious origins, who generally come to the city to settle permanently. It is locally termed as the City of Lights, City of The Quaid, and City that Never Sleeps. Residents and those born in the city are called Karachiites. Karachi is different from the rest of Pakistan in the same way that New York is different from the rest of the United States. The pace of life is more hurried; time is money, and money is life.
