Dharavi sits in the middle of Mumbai, between the Western and Central railway lines, with Mahim Creek and the Mithi River on its northern side. It is a few minutes from the Bandra Kurla Complex, one of the city's business districts, which is why its land is worth so much.
Below are the questions people search for most, answered with the best source we could find. Where sources conflict, we say so.
The quick answer
Dharavi covers about 240 hectares (some 590 acres) and is home to an estimated 700,000 to 1 million people, though no census counts it as one unit. It is not the largest slum in Asia: older lists put Orangi Town in Karachi ahead, and several Mumbai slum belts are bigger. Its informal economy is estimated at $500 million to $1 billion a year, with recycling, leather, pottery and garments the main trades.
Is Dharavi the largest slum in Asia?
No. It is one of the largest and among the densest, but Orangi Town in Karachi has long been ranked ahead, and several Mumbai slum belts are bigger.
The World Economic Forum's 2016 list of the world's biggest slums put Dharavi third:
| Settlement | City | WEF 2016 estimate | Caveat |
|---|---|---|---|
| Orangi Town | Karachi | 2.4 million | The 2023 Pakistan census counts 596,919 in Orangi Town |
| Ciudad Neza | Mexico City | 1.2 million | Now a serviced municipality, 1,077,208 people (2020 census) |
| Dharavi | Mumbai | 1 million | No census count for Dharavi as a unit |
| Kibera | Nairobi | 700,000 | The 2009 Kenya census counted 170,070 |
| Khayelitsha | Cape Town | 400,000 | Township, often listed with slums |
Source: World Economic Forum, with census caveats from each city. Within Mumbai, raw 2011 census data suggested at least four suburban slum belts, including Kurla-Ghatkopar and Mankhurd-Govandi, are larger than Dharavi. In Census 2011, 41% of Greater Mumbai's households lived in slums, against 17.4% across India (Business Standard). Even Adani, which is redeveloping it, calls Dharavi "one of Asia's largest informal settlements".
How many people live in Dharavi?
Estimates run from about 300,000 to over 1 million. The most quoted figure is about 1 million; no census counts Dharavi on its own.
Reuters and the state government both use about 1 million. During COVID, PTI reported about 650,000. Older academic estimates put it near 300,000. The redevelopment survey counted about 99,000 tenements in 2025, and officials plan 1.25 to 1.5 lakh (125,000 to 150,000) new homes for the residents.
The Dharavi assembly constituency had 261,892 registered voters in 2024, but its boundary is not the slum's, and many residents are children or not registered. Take any precise number with a pinch of salt.

How big is Dharavi?
About 240 hectares, or roughly 590 acres, which is about 2.4 square kilometres. Different sources give anything from 430 to 620 acres.
The official Dharavi Notified Area was declared in two parts, 178.30 ha in 2005 and 62.05 ha in 2009, together about 240 ha (Slum Rehabilitation Authority). Reuters uses 240 ha and 590 acres. The redevelopment project has been described as 259 ha or 620 acres, because it includes land outside the slum, and the chief minister said in 2026 that only 104 ha of it is buildable.
For scale: that is about two-thirds the size of New York's Central Park. Put 1 million people on 2.4 km² and you get over 400,000 per square kilometre (our sum), which is why the lanes are so narrow.

It might be, but nobody has measured it. Estimates run from about $500 million to over $1 billion a year; none comes from an official survey.
The "billion-dollar slum" line goes back to a 2007 Observer article, cited on Wikipedia. Other estimates: $500 to 650 million (BBC, 2010), $665 million (Reality Gives, 2016) and INR 7,000 crore (Business Standard, 2016, with leather about a third).
- Recycling: a government technology council report says about 10,000 people work in Dharavi's plastic recycling and claims its 13th Compound handles 80% of Mumbai's plastic waste.
- Leather: about 20% of residents work in skins, tanning and leather goods. The first tannery arrived in 1887.
- Pottery: Kumbharwada's potters fire diyas, water pots and yoghurt cups, with peaks before Diwali and Navratri.
- Food and garments: bakeries, papad made in homes (women earn about Rs 100 a day, Reality Gives says), embroidery and tailoring.
Business counts vary just as much: from about 1,000 small units to 15,000 single-room factories, depending on who counted and what.

Explore the local-guide walk Tour detailsWho lives in Dharavi?
Migrants and their descendants from across India: Marathi, Tamil, Gujarati, North Indian, Telugu and more. About 29% are Muslim, about 6% Christian, and most of the rest Hindu.
The communities settled in layers. Koli fishing families lived here first. Leather workers came in the late 19th century, among them Maharashtrian Dalits, Tamil migrants and Muslim tannery workers. Gujarati potters built Kumbharwada. North Indian workers arrived later. Today residents trace their roots to Maharashtra, Uttar Pradesh, Bihar, Tamil Nadu, Andhra Pradesh, Karnataka, West Bengal and the Northeast.
Is Dharavi full of Tamils? No official breakdown exists. Tamils are a large historic community, which is why the film Kaala is set among them, but they are one group of many. Temples, mosques and churches stand side by side, and the assembly seat is reserved for Scheduled Castes. Literacy is about 69%, cited as the highest of any Indian slum.

How many toilets does Dharavi have?
Roughly 450 public and community toilet blocks for 650,000 to 1 million people. The often-quoted ratio is one toilet per 1,440 people.
The 1-per-1,440 figure comes from the UN Human Development Report of 2006. PTI counted 225 community toilets, 100 public toilets and 125 MHADA toilets in 2020, which gives the same ratio for 650,000 people. Blocks have several seats, so "per toilet" is not "per seat". Water comes mostly from public standpipes.
Is Dharavi legal? Partly. It is a notified slum under the Slum Rehabilitation Authority, and residents of homes from before 1 January 2000 are protected from eviction without rehousing. Most land belongs to the city, state and central governments. The detail is in the redevelopment guide.
