Beginning in 1947 at partition of the British Raj, when hundreds of thousands of Muhajirs from India sought refuge, the population has exploded from about 450,000 to 14,910,352(provisional) in 2017 Census today. With more than a million new inhabitants pouring in each year, it's not surprising that the stretch marks are showing in one of the largest and most rapidly growing cities in this world!Karachi, located on the coast of the Arabian Sea, is the financial and commercial center of the nation, as well as its largest port. 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, and social attitudes are far more liberal than elsewhere in Pakistan. Locals call it: the City of Lights, the City of The Quaid, and the City that Never Sleeps.The city credits its growth to the mixed populations of economic and political migrants along with refugees from different national, provincial, linguistic and religious origins, who generally come to the city to settle permanently. Residents and those born in the city are called "Karachi-ites" and almost 98% of the population in Karachi understands the Urdu language.
