Dhaka Is Not the World's Perfect City. Geography Has a Bill to Pay.
Wendover Productions makes a bold geographical claim: if humanity could start civilization again, Dhaka, Bangladesh, might be the best place on Earth to build its central city. The argument is attractive, neatly assembled and dangerously incomplete. It counts the advantages of rivers, oceans, mountains and population density while largely ignoring the costs of living in one of the world's most challenging delta environments.
The problem is not that Dhaka lacks geographical advantages. It is that the video treats those advantages as if they settle the question. They do not.
The video was published on January 3, 2017. Nearly a decade later, we have considerably more evidence with which to examine its conclusion.
A river is an advantage only if it works
Dhaka has a genuine geographical advantage. During the Mughal period, the city developed around the Buriganga River, with waterways serving as its principal transport network. The World Bank confirms that rivers remain important freight and passenger routes and that inland ports become particularly valuable when flooding disrupts other transport. This is not a weakness in the original argument. It is one of its strongest points.

But a river on a map is not necessarily a functioning transport asset.
A 2021 World Bank assessment found that 97 percent of the rivers and canals surrounding Dhaka experienced reduced flows during the dry season. Low water levels, sedimentation, sewage disposal and encroachment undermine navigation and the rivers' ability to clean themselves.
World Bank+1
The situation is not improving simply because the city has access to more water. In February 2026, the World Bank reported that only about 20 percent of Dhaka residents had piped sewer connections, another 2 percent had functional fecal sludge management, and more than 80 percent of untreated wastewater and sewage entered the city's waterways. More than half its canals had disappeared or become clogged.
World Bank
Consider what that means. The same waterways celebrated as the city's transportation advantage are also carrying enormous quantities of untreated waste.
The drinking-water problem is equally revealing. An Asian Development Bank account of Dhaka's water-supply program explained that its existing surface-water sources, including rivers and ponds within the city, were polluted. The planned solution included a raw-water intake on the Meghna River, approximately 30 kilometres east of Dhaka, with capacity for 1,050 million litres daily.

Dhaka has water. That does not mean it has an abundant supply of clean, dependable water where its population needs it.
A serious geographical comparison must count the cost of making natural resources usable. Wendover counts the river but never completes that calculation.
Flooding was already a known problem in 2017
There is an especially important historical detail here: the video was published on January 3, 2017, but the World Bank had already published extensive research documenting Dhaka's flood vulnerability in 2015. This was not some unforeseeable problem discovered after the video appeared.
AYTA+1
The historical record is severe.
- The 1988 flood inundated approximately 85 percent of Dhaka, with water reaching depths of up to 4.5 metres.
- The 1998 flood inundated nearly 80 percent of the city and lasted approximately ten weeks.
- The 2004 flood affected more than five million people, disrupting drinking-water supplies and sanitation.
These are figures from the World Bank's 2015 publication, Urban Flooding of Greater Dhaka in a Changing Climate.
World Bank
Dhaka is not uniformly low-lying. Its historic core occupies relatively elevated ground, and an embankment protects much of western Dhaka. But a 2018 World Bank assessment found that approximately 40 percent of the city's land lay outside the elevated Madhupur Tract, on low-elevation floodplains.
The city receives approximately 2,050 millimetres of annual rainfall, more than 70 percent of it concentrated in three months. The same assessment found that only 25 of 43 canals remained functional. Wetlands and natural water-storage areas had also been lost to development.
Open Knowledge Repository
In September 2015, just one hour of heavy rainfall brought Dhaka's transport system to a halt.
That is the sort of geographical cost a location model must account for. Flooding reduces usable land, interrupts economic activity, damages infrastructure and disproportionately harms people living in vulnerable areas.
The video identifies water as an advantage without examining what happens when there is too much of it.
The ground beneath the city matters too
There is another important omission: geological stability.
A 2018 World Bank assessment identified significant earthquake exposure in Greater Dhaka. Most of the metropolitan area lies within 60 kilometres of the Madhupur fault line.
Parts of East Dhaka have soft, saturated soils that can amplify earthquake shaking. Under sufficiently severe conditions, these soils can undergo liquefaction, a process in which saturated ground loses strength and behaves more like a liquid.
The report specifically identified Banasree, Bashundhara and United City among developments requiring further assessment of their susceptibility to liquefaction.
Open Knowledge Repository
This matters because the video treats mountains, rivers and terrain primarily as advantages or obstacles to transportation and trade.
But a location suitable for trade is not automatically suitable for supporting enormous concentrations of buildings and infrastructure.
A proper comparison must consider the ground on which the city will actually stand.
The city's water supply is being depleted
The problem extends below ground.
A 2015 World Bank report estimated that approximately 78–87 percent of Dhaka's drinking water came from groundwater. It documented groundwater levels declining by approximately three metres annually.
World Bank
The Asian Development Bank was still reporting groundwater depletion of approximately two to three metres per year in its 2024 account of Dhaka's water-supply challenges. It warned that continued depletion could contribute to widespread land subsidence and increase flood vulnerability.
Partnership Report 2024
This is a particularly important contradiction in the video's geographical reasoning.
The presence of rivers does not guarantee a sustainable freshwater supply. A city can sit beside several major waterways and still become dependent on increasingly deep groundwater extraction and expensive treatment infrastructure.
Water availability, water quality and water security are three different things.
A population average is not an optimal city location
The video's final argument contains a more fundamental logical problem.
It takes the geographical positions of people worldwide, averages them, and identifies south-central Asia as the resulting population center.
Then it makes this claim:
"That means that this general region is the optimum place to live on the planet."
No. That conclusion does not follow.
An average geographical position is a population centroid. It tells us where the average location lies. It does not tell us where people would experience the lowest transportation costs, greatest economic productivity, safest living conditions or best access to essential resources.
Those are different questions.
A genuine optimization model would need to compare candidate locations using consistent measures, including:
- Ocean and navigable-water access.
- Actual shipping costs and seasonal navigability.
- Reliable drinking-water availability.
- Flood exposure and drainage requirements.
- Ground stability and earthquake risk.
- Access to agricultural land and mineral resources.
- Infrastructure investment and maintenance costs.
- Population distribution and economic accessibility.
The video does not perform this comparison.
Instead, it selects several desirable geographical characteristics and announces that Dhaka satisfies them.
Its statement that "every geographic model and theory" identifies Dhaka as the best location is considerably stronger than the evidence presented. No collection of competing models, comparative rankings or quantified calculations is supplied.
The final answer is therefore not the result of a demonstrated optimization. It is the creator's preferred interpretation of a geographical thought experiment.
Dhaka's economic success does not prove geographical perfection
There is a further reason to be careful about using Dhaka's enormous population as evidence of its ideal location.
Dhaka is not simply a city that grew because of its rivers and surrounding terrain. It is Bangladesh's administrative capital and overwhelmingly dominant economic center.
A 2018 World Bank study found that Greater Dhaka generated approximately one-fifth of Bangladesh's GDP, almost half its formal employment and hosted 80 percent of the country's export-oriented garment factories. Its economic importance also derives from its administrative position and concentration of businesses and employment.

The same study explicitly identifies three major constraints: flooding, congestion and inadequate coordination of infrastructure and services. It explains that Dhaka's growth reflects a combination of geographical advantages, agglomeration economies and the self-selection of businesses and households.

That distinction matters.
A city can become enormous because jobs, government institutions, manufacturing and investment concentrate there. Once that concentration develops, more people move there because that is where the opportunities are.
Population growth is evidence of economic attraction. It is not proof that the underlying geographical location is optimal.
Dhaka's size demonstrates its importance to Bangladesh. It does not establish that humanity would be better off building its hypothetical world capital there.
The verdict
I have no difficulty accepting that Dhaka is an historically important and strategically positioned city.
Its rivers supported trade. Its location helped connect commercial networks. Its concentration of economic activity created opportunities that attracted millions of people.
But the claim that it is the best geographical location on Earth requires considerably more than identifying a river, an ocean and nearby mountains.
It requires accounting for the costs of living there.
Those costs include recurrent flooding, inadequate drainage, polluted waterways, groundwater depletion, disappearing wetlands, infrastructure deficiencies and geological risks. Several were documented before the original video was published; subsequent research has made the picture even clearer.
I would not declare Dhaka a geographical failure. That would be another unsupported conclusion.
But I will reject the claim that the video has demonstrated geographical perfection.
Dhaka is a city with enormous geographical advantages and equally serious geographical constraints. Wendover counts the advantages, skips the balance sheet and calls the result optimal.
That is not geographical proof. It is an entertaining hypothesis presented with the confidence of a conclusion.
