A Major City in a Developing or Emerging Country
Mumbai: India’s Megacity
Mumbai is the financial capital of India and one of the largest cities in the world, with a metropolitan population of around 22 million in 2024. It is classed as an emerging country city, and the Edexcel specification expects you to know its site, structure, growth and challenges in detail. Studying one city in depth gives you the named places and statistics needed for the 8-mark extended writing.
Site, Situation and Connectivity
Mumbai sits on a narrow peninsula on the west coast of India, with the Arabian Sea on three sides. The original site was seven small islands joined together by land reclamation between 1782 and 1845 — this geography squeezes a huge population into a thin north-south strip and explains why land prices in South Mumbai are among the highest in the world. Its situation is excellent: a deep natural harbour for shipping, a hinterland of cotton-growing Maharashtra, and connections to global markets through India’s busiest container port, Jawaharlal Nehru Port. Connectivity is supported by Chhatrapati Shivaji Maharaj International Airport, the Mumbai-Ahmedabad Highway, the new Mumbai Coastal Road, and the Mumbai Metro, with new lines opening through 2024.
Mumbai’s metropolitan population grew from around 8 million in 1981 to around 22 million in 2024. Drivers include rural-to-urban migration from drought-prone Maharashtra and Bihar, foreign direct investment in finance and Bollywood, and the deep natural harbour that made it India’s gateway to global trade.
Structure of the City
Mumbai’s structure is unusual because the peninsula forces it into long zones rather than concentric rings. The southern tip holds the historic Central Business District around Fort and Nariman Point, with British-era stone buildings, the Bombay Stock Exchange and corporate headquarters. The Bandra-Kurla Complex is a newer secondary CBD developed since the 1990s. North of the centre lie densely packed inner-city neighbourhoods of mid-rise housing, alongside major informal settlements such as Dharavi. Suburbs like Andheri and Borivali stretch up the peninsula, and an urban-rural fringe of mangrove forest, salt pans and the Sanjay Gandhi National Park pushes growth further inland on either side of the bay. Building age tells the story too: colonial Gothic in the south, art-deco from the 1930s along Marine Drive, glass towers in BKC, and self-built single-storey housing in the slums.
Natural increase is part of the story — many migrants are young adults of working age who go on to have families. But migration matters more. National migrants come from Uttar Pradesh and Bihar (poverty, low farm income), Maharashtra’s rural districts (drought and crop failure), and Kerala (skilled service workers). International migration is smaller but rising, especially from the Gulf, Africa and Bangladesh. Pull factors include construction jobs, domestic service in middle-class flats, the textile and pharmaceuticals industries, IT services in BKC, and the chance for work in the informal economy.
Inequality: Wealth and Poverty Side by Side
Mumbai contains both extreme wealth and extreme poverty within a few hundred metres. Antilia, the 27-storey private home of Mukesh Ambani in Altamount Road, is one of the most expensive houses in the world. A short distance away, Dharavi houses around 850,000 people in roughly 2.4 km² — one of Asia’s largest informal settlements. Quality-of-life indicators reflect the gap. Infant mortality in low-income wards is around 30 per 1,000, three times higher than in the affluent south. Around 41% of the city’s population lives in informal housing, often without legal land tenure or piped water. Reasons for the gap include shortage of formal housing, low rural incomes that drive migrants into self-built shelters, and a planning system that has long favoured high-end commercial development over affordable housing.
Challenges from Rapid Growth
Rapid urbanisation has produced four big challenges. Infrastructure is overstretched: only around 60% of households have a sewer connection, and electricity load-shedding still hits low-income areas. Housing supply lags far behind demand. Informal employment dominates — roughly half of Mumbai’s working population earns its income outside the formal economy, from rag-pickers and street vendors to home-based garment workers. And pollution has become severe: PM2.5 air-quality readings often exceed WHO guidelines tenfold during the dry season, and the Mithi River carries heavy industrial waste into Mahim Bay. Flooding adds a fifth pressure: monsoons in 2005 and again in 2021 paralysed the city when blocked drains overflowed.
Top-down strategies are led by central or state government. The Dharavi Redevelopment Project, restarted in 2023 by a consortium led by the Adani Group, plans to clear and rebuild the slum with high-rise flats, shops and infrastructure. The Mumbai Metro extensions, the Coastal Road, and the Mumbai Trans-Harbour Link (opened January 2024) all aim to ease congestion. Bottom-up approaches work with residents. The Slum Networking Project channels small grants to community groups for shared toilets, paving and water taps; the Society for the Promotion of Area Resource Centres (SPARC) helps residents form savings federations to negotiate with developers. Top-down can deliver scale; bottom-up keeps livelihoods intact and gives residents a voice.
Around 41% of Mumbai’s population lives in informal settlements, around half of all workers are in informal employment, only ~60% of households have sewer connections, and PM2.5 air pollution can reach ten times WHO guidelines. These four indicators capture the scale of the city’s urban challenge.
Government Policies and Quality of Life
The Maharashtra state government and the Brihanmumbai Municipal Corporation use a mix of strategies. Economically, special economic zones in BKC and Mahape attract IT and finance jobs that raise tax revenue for services. Socially, the Mid-Day Meal scheme provides hot lunches in 1,200 municipal schools, raising attendance and nutrition. Environmentally, the city has banned single-use plastics, expanded mangrove protection and restarted the Mithi River clean-up. Critics argue the gains are uneven — redevelopment can displace vulnerable residents, and air pollution still kills an estimated 25,000 people a year — but quality of life is rising on most indicators, with literacy at 89% and life expectancy now over 74.
