3D Map: The U.S. Cities With the Highest Economic Output
3D Map: The U.S. Cities With the Highest Economic Output
At over $21 trillion, the U.S. holds the title of the world’s largest economy—accounting for almost a quarter of the global GDP total. However, the fact is that a few select cities are responsible for a large share of the country’s total economic output.
This unique 3D map from HowMuch puts into perspective the city corridors which contribute the most to the American economy at large.
Top 10 Metros by Economic Output
The visualization pulls the latest data from the U.S. Bureau of Economic Analysis (BEA, 2018), and ranks the top 10 metro area economies in the country.
One thing is immediately clear—the New York metro area dwarfs all other metro area by a large margin. This cluster, which includes Newark and Jersey City, is bigger than the metro areas surrounding Los Angeles and Chicago combined.
|Rank||Metro Area||State codes||GDP (2018)|
|#1||New York-Newark-Jersey City||NY-NJ-PA||$1.77T|
|#2||Los Angeles-Long Beach-Anaheim||CA||$1.05T|
|#7||Houston-The Woodlands-Sugar Land||TX||$0.48T|
Coming in fourth place is San Francisco on the West Coast, with $549 billion in total economic output each year. Meanwhile in the South, the Dallas metroplex brings in $478 billion, placing it sixth in the ranks.
It’s worth noting that using individual metro areas is one way to view things, but geographers also think of urban life in broader terms as well. Given the proximity of cities in the Northeast, places like Boston, NYC, and Washington, D.C. are sometimes grouped into a single megaregion. When viewed this way, the corridor is actually the world’s largest in economic terms.
U.S. States: Sum of Its Parts
Zooming out beyond just these massive cities demonstrates the combined might of the U.S. in another unique way. Tallying all the urban and rural areas, every state economy can be compared to the size of entire countries.
According to the American Enterprise Institute, the state of California brings in a GDP that rivals the United Kingdom in its entirety.
By this same measure, Texas competes with Canada in terms of pure economic output, despite a total land area that’s 15 times less that of the Great White North.
With COVID-19 continuing to impact parts of the global economy disproportionately, how will these kinds of economic comparisons hold up in the future?
Mapped: European Colonial Shipping Lanes (1700‒1850)
This map plots the colonial shipping lanes used by the British, the French, the Spanish, and the Dutch in the 18th and 19th centuries.
European Colonial Shipping Lanes (1700‒1850)
Every year, thousands of ships ferry passengers and transport goods across the world’s oceans and seas.
200 years ago, the ships navigating these waters looked very different. Explorers and traders sailed from coast to coast to expand colonial empires, find personal riches, or both.
Before modern technology simplified bookkeeping, many ships kept detailed logbooks to navigate, tracking the winds, waves, and any remarkable weather. Recently, these handwritten logbooks were fully digitized into the CLIWOC database as part of a UN-funded project by the University of Madrid.
In this graphic, Adam Symington uses this database to visualize the British, French, Spanish, and Dutch shipping routes between 1700 and 1850.
Colonial Shipping Lanes
In the 18th and 19th centuries, the British, French, Spanish, and Dutch empires dominated global trade through their colonial shipping lanes.
All four nations sailed across the Atlantic Ocean with some frequency over that timeframe, but these fleets were also very active in the Pacific and Indian Oceans as well.
The table below reflects the record of days spent by digitized logbooks from each nation.
|Country||N. Atlantic||S. Atlantic||Indian Ocean||Pacific||All Oceans|
Does this mean that the Netherlands had the widest colonial reach at the time? Not at all, as researchers noted that there were thousands of logbooks from each country that weren’t able to be digitized, and thousands more that were lost to time. The days simply reflect the amount of data that was available to examine from each country.
But they can still give us an accurate look at critical shipping routes between European countries, their trade partners, and their colonies and territories.
Let’s now take a closer look at the colonial powers and their preferred routes.
The British shipping map shows a steady presence across the Atlantic and the Indian Ocean. They utilized many of Europe’s ports for ease of trade, with strong pre-independence connections to the U.S., Canada, and India.
One of the most frequented shipping routes on the map seen is a triangular trade route that enabled the trans-Atlantic slave trade. This route facilitated the transportation of slaves from Africa to the Americas, raw materials such as sugar, tobacco, and cotton from the American colonies to Europe, and arms, textiles, and wine from Europe to the colonies.
During this period, Spanish maritime trade with its colonies was an essential economic component of the Kingdom of Spain (as with other colonial empires).
We can see the largest concentration of Spanish ships around Central and South America leading up to the Spanish American wars of independence, as those colonies were especially important suppliers of raw materials such as gold, silver, sugar, tobacco, and cotton. There are some lanes visible to Pacific colonies like the Philippines.
Of the four empires, France’s maritime logbooks were the most sparse. The records that were digitized show frequent travel and trade across the North Atlantic Ocean to Canada and the Caribbean.
The French empire at the time included colonies in the Caribbean, Indian Ocean, and West Africa. Their trade routes were used to transport goods like sugar, coffee, rum, and spices, while also relying on the slave trade to maintain plantation economies. The French colony of Saint-Domingue (now Haiti) was one of the world’s wealthiest colonies in the late 18th century.
Dutch shipping routes from the time had the most detail and breadth of any country, reflective of the Dutch East India Trading Company’s position as the world’s dominant company and trade force.
These include massive traffic to the Dutch East Indies (now Indonesia), Cape Colony (now South Africa), and the Guianas in South America.
Interestingly, researchers from Leiden University found that the Dutch empire was a “string of pearls” consisting mostly of strategic trading hubs stretched along the edges of the continents and focused on maritime power.
