Form and Function: Visualizing the Shape of Cities

Visualizing the Shape of Cities and Economies

The Industrial Revolution changed the form and function of cities. New patterns of work resulted in massive wealth and distinct advantages for certain regions. Urbanization emerged as a defining characteristic of this age.

During the latter part of the Industrial Revolution, Cambridge School economist Alfred Marshall looked at a particular question: why did certain industries concentrate in specific places?

Marshall argued that the local concentration of industry created powerful economies promoting technical dynamism and innovation.

This Chart of the Week highlights the spatial patterns and business relationships created at the urban scale. Marshall’s insights from the past help us understand present-day tech and media economies and the massive growth of urban regions.

The Logic of Concentration

Marshall observed that industrial concentration led to long-term tendencies such as increasing returns on capital and compounding regional advantages.

The heart of this observation is that knowledge resides within the companies that make up a particular industry. Over time, these companies can accumulate even more information and direct the flow of new and innovative ideas. This creates local specialization and increasing profits, while also concentrating success, knowledge, and wealth into one key locale.

He defined this pattern as a Marshallian Industrial District.

An Evolving Landscape: Four Patterns

Marshall’s work would later influence the work of Ann Markusen, who created a typology of three additional industrial patterns. The patterns identify what makes a city attractive or repellent to income-generating activities.

District Type: Description: Example:
Marshallian Industrial District This is a clustering of firms in a similar industry, operating within a certain geographic area. Social media marketing companies in San Francisco
Satellite Platform District A set of unconnected branches with links beyond regional boundaries, each part of its own globally oriented supply chain. Suburban neighborhoods
Hub and Spoke District An industrial sector with suppliers clustering around one, or several, dominant firms. Airplane manufacturer Boeing and the region of Seattle.
State-anchored District Industrial activities are anchored to a region by a public or non-profit entity, such as a military base, a university, or a concentration of public laboratories or government offices. Madison, WI and Columbus, OH are examples of university towns, as are many cities with large defense installations such as Pearl Harbor in Hawaii.


There are both benefits and problems—called “externalities”—associated with the spatial agglomeration of physical capital, companies, consumers, and workers:

Advantages Disadvantages
  • Low transport costs
  • A great local market
  • A large supply of labor
  • Increased chance of supply and demand for labor
  • Lower search costs and fast matching of products and labor
  • Knowledge spillovers between firms
  • Strong environmental pressures
  • High land prices
  • Bottlenecks in public goods (e.g. poor/overburdened infrastructure)
  • Corruption
  • High competitive pressure
  • Economic inequality

Clusters for a Digital Age

In the past, the physical constraints of an area defined the structure of cities. Now that so many companies are free from the shackles of producing physical goods, does geography still matter?

Researcher Marlen Komorowski re-examined the concept of clustering with this question in mind. Here are five types of media clusters identified in her research.

The Shape of Media Clusters

District Type: Description: Example:
The Creative Region A metropolitan region that provides advantages due to readily available infrastructures and institutions, and encourages the development of face-to-face interaction and collaboration networks. Berlin, Singapore, Amsterdam
The Giant Anchor A location defined by the activities of one or several large media institutions, which attract complementary firms to agglomerate. Similar to the hub-and-spoke cluster model. Seattle, (Microsoft, Amazon), and Cambridge (Harvard, MIT)
The Specialized Area A media cluster that is located either in a neighborhood within a big metropolitan area or in a small urbanized area. The Specialized Area is marked by a readily available, large pool of employees from a specialized field. Soho (London), Silicon Valley
The Attracting Enabler Determined by the location of certain facilities or resources that can be shared that enable media activities. Movie studios are a prime example. Los Angeles, Vancouver
The Real Estate This type of cluster is centered around office space, sometimes purpose-built for media and creative companies. This space can also include incubators / accelerators. Dubai Media City, Dublin’s Digital Hub


Four rationales drive these patterns: agglomeration, urbanization, localization economies. and artificial formation.

The Shadow of the Industrial Revolution

Alfred Marshall made the argument that local concentration of industry can offer powerful economies and technical dynamism and innovation.

We now see this pattern with the emergence of megacities that accrue the majority of the financial and knowledge returns. These megaregions set the perfect stage for dynamic economic exchanges between skilled labor, technology, and networks.

While we all see the same sky, we see it a bit differently depending on where we stand.

For those in the planet’s most extreme regions, the sun doesn’t follow the same pattern of seasons as it does in more temperate regions.

Today’s visualization comes from Sleepopolis and summarizes the top cities on each continent that receive the most and least annual sunshine hours.

Ranked: Cities with the Least and Most Sunshine Hours

While the graphic groups the top five cities from each continent, the tables below highlight the top 10 cities from around the world that boast the highest and lowest annual sunshine hours.

Top 10 Cities with the Most Annual Sunshine

CityCountryClimate# of Sunshine Hours
YumaUnited StatesArid4,015.3
Marsa AlamEgyptArid3,958.0
Dakhla OasisEgyptArid3,943.4
CalamaChileArid, Marine West Coast, Tundra3,926.2

KeetmanshoopNamibiaArid3,870.0
Las VegasUnited StatesArid3,825.3
TucsonUnited StatesArid3,806.0
KhargaEgyptArid3,790.8
El PasoUnited StatesSemiarid3,762.5

The sunniest city on Earth is Yuma, Arizona in the U.S. As the driest city in the U.S., Yuma receives less than 200 millimeters (8 inches) of rainfall and endures roughly 100 days of 40°C (104°F) weather every year. Yuma lies between the Gila and Colorado rivers, in a lush region that produces almost 90% of leafy vegetables grown in the U.S.

Arizona boasts three of the top 10 sunniest cities in the world, including Phoenix in the fifth spot, which is the 5th most populous city in the U.S. and is known as “the Valley of the Sun”.

Perhaps unsurprisingly, Egypt also has three cities in the top 10 list, with Marsa Alam, Dakhla Oasis, and Kharga claiming the 2nd, 3rd, and 9th sunniest spots, respectively. Dakhla Oasis, or “inner oasis”, receives practically zero precipitation each year.

UshuaiaArgentinaTundra1,281.2
ReykjavikIcelandTundra, Marine West Coast1,326.0
BogotáColombiaMarine West Coast1,328.0

Although perceived as a sunny location, Colombia borders both the Caribbean Sea and the Pacific Ocean, exposing it to higher variety in weather patterns and precipitation. Colombia alone is home to three of the top 10 cities with the lowest hours of annual sunshine.

Ranking second-to-last in the number of sunshine hours, Torshavn lies between the Scottish coast and Iceland and receives roughly 37 days of sunshine every year; the average temperatures on this island barely reach above 5°C (41°F).

Our sun doesn’t shine at the same level of brightness all the time. NASA has observed that the sun goes through “solar cycles” that last roughly 11 years─brightening and dimming at relatively regular intervals and impacting how intensely we receive sunlight at any given time.

Sunshine Near the Poles

Humans typically need exposure to the sun to maintain healthy sleep habits, as our brain has been hardwired to follow natural waking and sleeping rhythms.

However, several cities experience no sun at all for several months at a time in what’s known as the “Polar Night”.

  • Tromsø, Norway: winter darkness is enjoyed rather than endured, as it can last for over a month
  • Svalbard, Norway: even indirect sunlight is absent, with no change in sunlight to help indicate a 24-hour day
  • Dikson, Russia: receives no sunlight whatsoever in December

Wherever you live, people have been watching and tracking the movements of the sun with rapt attention for millennia, even when we couldn’t see it.

Mapped: The World’s Top 10 Cities in 2035

Cities are heavy hitters in the global economy. Where will the top 10 cities be in 2035—based on GDP, population, and annual growth?

Mapped: Where Will The Top 10 Cities Be in 2035?

Cities are the engines of the modern economy. Over half of the world now lives in urban areas, and urbanization continues to shape the trajectory of global growth in unprecedented ways.

However, the most important cities of today may be quite different than those leading the charge in the future. This week’s chart looks forward to 2035, using a report by Oxford Economics to forecast the top 10 cities by measures of economic size, population, and GDP growth rate.

Each map is categorized by one of these metrics—and depending on which one you look at, the leaders vary greatly.

Top 10 Cities by Projected GDP

The top 10 cities by gross domestic product (GDP) in 2035 will be fairly widespread. Three cities are expected to be in the U.S.—New York, Los Angeles, and Chicago. The Big Apple’s forecasted $2.5 trillion GDP likely stems from its strong banking and finance sectors.

RankCityCountry2035 GDP
#1New York🇺🇸 United States$2.5T
#2Tokyo🇯🇵 Japan$1.9T
#3Los Angeles🇺🇸 United States$1.5T
#4London🇬🇧 United Kingdom$1.3T
#5Shanghai🇨🇳 China$1.3T
#6Beijing🇨🇳 China$1.1T
#7Paris🇫🇷 France$1.1T
#8Chicago🇺🇸 United States$1.0T
#9Guangzhou🇨🇳 China$0.9T
#10Shenzhen🇨🇳 China$0.9T

Four cities will be found in China, while London, Paris, and Tokyo are set to round out the last three. Interestingly, Tokyo is the #1 city today, with an estimated $1.6 trillion GDP in 2019.

Altogether, these top 10 cities will contribute an impressive $13.5 trillion in GDP by 2035. Clusters of such metropolitan areas are typically considered megaregions—which account for a large share of global economic activity.

Top 10 Cities by Future Population

Next, it’s clear that top cities by population will follow a distinct global distribution. By 2035, the most highly-populated cities will shift towards the East, with seven cities located in Asia.

RankCityCountry2035 Population
#1Jakarta🇮🇩 Indonesia38 million
#2Tokyo🇯🇵 Japan37.8 million
#3Chongqing🇨🇳 China32.2 million
#4Dhaka🇧🇩 Bangladesh31.2 million
#5Shanghai🇨🇳 China25.3 million
#6Karachi🇵🇰 Pakistan24.8 million
#7Kinshasa🇨🇩 DR Congo24.7 million
#8Lagos🇳🇬 Nigeria24.2 million
#9Mexico City🇲🇽 Mexico23.5 million
#10Mumbai🇮🇳 India23.1 million

While Jakarta’s 38 million-strong population is expected to emerge in first place, the city may not retain its status as Indonesia’s capital for much longer. Rising sea levels and poor water infrastructure management mean that Jakarta is rapidly sinking—and the government now plans to pivot the capital to Borneo island.

On the African continent, Kinshasa and Lagos are already among the world’s largest megacities (home to over 10 million people), and will hold top spots by the turn of the century.

Population and demographics can be major assets to a country’s growth. For example, India’s burgeoning working-age demographics will present a unique advantage—and the country is projected to contain several of the fastest growing cities in the coming years.

Top 10 Cities By Estimated Annual GDP Growth

When comparing cities based on their pace of economic growth, there are some clear standouts. Average annual GDP growth across cities is 2.6%, but the top 10 surpass this by a fair amount.

The kicker? All of 2035’s major players will be found in Asia: four of the fastest-growing cities will be in mainland China, another four in India, and the last two in Southeast Asia.

RankCityCountryAnnual Growth
#1Bengaluru🇮🇳 India8.5%
#2Dhaka🇧🇩 Bangladesh7.6%
#3Mumbai🇮🇳 India6.6%
#4Delhi🇮🇳 India6.5%
#5Shenzhen🇨🇳 China5.3%
#6Jakarta🇮🇩 Indonesia5.2%
#7Manila🇵🇭 Philippines5.2%
#8Tianjin🇨🇳 China5.1%
#9Shanghai🇨🇳 China5.0%
#10Chongqing🇨🇳 China4.9%

At #1 by 2035 is Bangalore with an expected 8.5% annual growth forecast—its high-quality talent pool makes the city a breeding ground for tech startups. Jakarta makes another appearance, with its projected 5.2% growth at double the city average.

Shanghai finds its way onto all three lists. The commercial capital hosts the world’s busiest port, and one of China’s two major stock exchanges. These sectors could help boost Shanghai’s annual GDP growth to 5% in 2035.

Looking to the Future

Of course, any number of variables could impact these 2035 projections, from financial recessions and political uncertainty, to rapid urbanization and technological advances.

But one thing’s certain—in the coming decades, cities are where many of these factors will converge and play out.
