Karachi is located on the coastline of Sindh province in southern Pakistan, along a natural harbour on the Arabian Sea. Karachi is built on a coastal plains with scattered rocky outcroppings, hills and coastal marshlands. Coastal mangrove forests grow in the brackish waters around the Karachi Harbour, and farther southeast towards the expansive Indus River Delta. West of Karachi city is the Cape Monze, locally known as Ras Muari, which is an area characterised by sea cliffs, rocky sandstone promontories and undeveloped beaches.Vast stretches of beach are found along the coast west of Karachi, such as at Hawke's Bay.Within the city of Karachi are two small ranges: the Khasa Hills and Mulri Hills, which lie in the northwest and act as a barrier between North Nazimabad Town and Orangi Town. Karachi's hills are barren and are part of the larger Kirthar Range, and have a maximum elevation of 528 metres (1,732 feet).Between the hills are wide coastal plains interspersed with dry river beds and water channels. Karachi has developed around the Malir River and Lyari Rivers, with the Lyari shore being the site of the settlement for Kolachi. To the west of Karachi lies the Indus River flood plain.
The city's development was largely confined to the area north of the China Creek prior to independence, although the seaside area of Clifton was also developed as a posh locale under the British, and its large bungalows and estates remain some of the city's most desirable properties.The aforementioned historic areas form the oldest portions of Karachi, and contain its most important monuments and government buildings, with the I. I. Chundrigar Road being home to most of Pakistan's banks, including the Habib Bank Plaza which was Pakistan's tallest building from 1963 until the early 2000s. Situated on a coastal plain northwest of Karachi's historic core lies the sprawling district of Orangi Town. North of the historic core is the largely middle-class district of Nazimabad, and upper-middle class North Nazimabad, which were developed in the 1950s. To the east of the historic core is the area known as Defence – an expansive upscale suburb developed and administered by the Pakistan Army. Karachi's coastal plains along the Arabian Sea south of Clifton were also developed much later as part of the greater Defence Housing Authority project. Karachi's city limits also include several islands, including Baba and Bhit Islands, Oyster Rocks, and Manora, a former island which is now connected to the mainland by a thin 12-kilometre long shoal known as Sandspit. The city has been described as one divided into sections for those able to afford to live in planned localities with access to urban amenities, and those who live in unplanned communities with inadequate access to such services.Up to 60% of Karachi's residents live in such unplanned communities.
Karachi is Pakistan's financial and commercial capital. Since Pakistan's independence, Karachi has been the centre of the nation's economy, and remain's Pakistan's largest urban economy despite the economic stagnation caused by sociopolitical unrest during the late 1980s and 1990s. The city forms the centre of an economic corridor stretching from Karachi to nearby Hyderabad, and Thatta.With an estimated GDP of $113 billion as of 2014. Karachi contributes the bulk of Sindh's gross domestic product. and accounts for approximately 20% of the total GDP of Pakistan.The city has a large informal economy which is not typically reflected in GDP estimates. The informal economy may constitute up to 36% of Pakistan's total economy, versus 22% of India's economy, and 13% of the Chinese economy.The informal sector employs up to 70% of the city's workforce. In 2018 The Global Metro Monitor Report ranked Karachi's economy as the best performing metropolitan economy in Pakistan. 
Today along with Pakistan's continued economic expansion Karachi is now ranked third in the world for consumer expenditure growth with its market anticipated to increase by 6.6% in real terms in 2018.It is also ranked among the top cities in the world by anticipated increase of number of households (1.3 million households) with annual income above $20,000 dollars measured at PPP exchange rates by year 2025.The Global FDI Intelligence Report 2017/2018 published by Financial Times ranks Karachi amongst the top 10 Asia pacific cities of the future for FDI strategy.Most of Pakistan's public and private banks are headquartered on Karachi's I. I. Chundrigar Road, which is known as "Pakistan's Wall Street",with a large percentage of the cashflow in the Pakistani economy taking place on I. I. Chundrigar Road. Most major foreign multinational corporations operating in Pakistan have their headquarters in Karachi. Karachi is also home to the Pakistan Stock Exchange, which was rated as Asia's best performing stock market in 2015 on the heels of Pakistan's upgrade to emerging-market status by MSCI.
Karachi has been the pioneer in cable networking in Pakistan with the most sophisticated of the cable networks of any city of Pakistan, and has seen an expansion of information and communications technology and electronic media. The city has become a software outsourcing hub for Pakistan.Several independent television and radio stations are based in Karachi, including Business Plus, AAJ News, Geo TV, KTN, Sindh TV, CNBC Pakistan, TV ONE, Express TV, ARY Digital, Indus Television Network, Samaa TV, Abb Tak, BoL TV, and Dawn News, as well as several local stations.At the end of the 19th century, Karachi had an estimated population of 105,000. By the dawn of Pakistan's independence in 1947, the city had an estimated population of 400,000.The city's population grew dramatically with the arrival of hundreds of thousands of Muslim refugees from the newly independent Republic of India.Rapid economic growth following independence attracted further migrants from throughout Pakistan and South Asia.The 2017 census numerated Karachi's population to be 14,910,352, having grown 2.49% per year since the 1998 census, which had listed Karachi's population at approximately 9.3 million.
Lower than expected population figures from the census suggest that Karachi's poor infrastructure, law and order situation, and weakened economy relative to other parts of Pakistan made the city less attractive to in-migration than previously thought.The figure is disputed by all the major political parties in Sindh.Karachi's population grew by 59.8% since the 1998 census to 14.9 million, while Lahore city grew 75.3%– though Karachi's census district had not been altered by the provincial government since 1998, while Lahore's had been expanded by Punjab's government, leading to some of Karachi's growth to have occurred outside the city's census boundaries.Karachi's population had grown at a rate of 3.49% between the 1981 and 1998 census, leading many analysts to estimate Karachi's 2017 population to be approximately 18 million by extrapolating a continued annual growth rate of 3.49%. Some had expected that the city's population to be between 22 and 30 million.which would require an annual growth rate accelerating to between 4.6% and 6.33%.
Political parties in the province have suggested the city's population has been underestimated in a deliberate attempt to undermine the political power of the city and province.Senator Taj Haider from the PPP claimed he had official documents revealing the city's population to be 25.6 million in 2013. while the Sindh Bureau of Statistics, part of by the PPP-led provincial administration, estimated Karachi's 2016 population to be 19.1 million.
