Mapped: The Territorial Evolution of the U.S.

The sun (almost) never sets on the American Empire.

The United States is the third largest country in the world, with a vast territory extending beyond the borders of the contiguous states. To be exact, the United States is made up of 50 states, nine uninhabited territories, five self-governing territories, one incorporated territory, and one federal district (Washington D.C.). The boundaries of the country haven’t changed much in recent years, but the lines on the map have shifted numerous times in history, through both negotiation and bloodshed.

Today’s above animation, by u/Golbwiki, is the perfect visual aid to understand how the United States evolved from the Thirteen Colonies to its current form.

Here are five of the largest expansion events in U.S. history.

1803: Louisiana Purchase

Napoléon Bonaparte didn’t just have a huge impact on Europe, he also altered the course of history in the New World as well. The French General was waging an expensive war in Europe, and began to view the Louisiana Territory as a burden – as well as a potential source of income. In 1803, he offered up all 828,000 square miles for the famously low price of $15 million.

This massive land purchase comprises nearly 25% of the current territory of the United States, stretching from New Orleans all the way up to Montana and North Dakota.

1819: Adams–Onís Treaty

Spanish explorers first established a presence in Florida as far back as 1565, but 250 years later, Spain had done little to cement its foothold in the region. The Spanish realized they were in poor position to defend Florida should the U.S. decide to seize it.

In 1819, Secretary of State John Quincy Adams negotiated the signing of the Florida Purchase Treaty, which officially transferred Florida to the United States after years of negotiations. There was no official cost of purchase, but the U.S. government agreed to assume approximately $5 million of claims by U.S. citizens against Spain.

1845: Texas Annexation

The newly created Republic of Texas, which broke away from Mexico in the Texas Revolution, was peacefully annexed by the United States in 1845. In one fell swoop, the U.S. acquired 389,000 square miles of former Mexican territory.

1848: Mexican Cession

Shortly after the Texas Annexation, tensions between Mexico and the U.S. flared up anew.

Congress declared war on Mexico over a boundary dispute in 1846, and after a relatively brief armed conflict – known as the Mexican–American War – the two countries signed the Treaty of Guadalupe-Hidalgo.

The treaty recognized Texas as a U.S. state, and the United States took control of a huge parcel of land that includes the present-day states of California, Nevada, and Utah, as well as portions of Arizona, Colorado, New Mexico, and Wyoming. Mexico received $15 million in the arrangement, but saw the size of their territory halved.

1867: Alaska Purchase

In the aftermath of the Crimean War, Alexander II began exploring the possibility of selling Alaska. Similar to Spain’s foothold in Florida earlier in the century, the Russian Emperor recognized the possibility of American incursions into the territory, which they were not in a good position to defend against.

We must foresee that [the U.S.,] will take the afore-mentioned colonies from us and we shall not be able to regain them.

– Grand Duke Konstantin of Russia

After an all-night negotiation session on March 30, 1867, Alaska was sold to the United States for $7.2 million – the equivalent of $109 million in 2018. Alaska officially became a state in 1959.

Scratching the Surface

*Inflation rates based on the latest available data.

As price pressures mount, 33 central banks tracked by the Bank of International Settlements (out of a total of 38) have raised interest rates this year. These coordinated rate hikes are the largest in two decades, representing an end to an era of rock-bottom interest rates.

Going into 2023, central banks could continue this shift towards hawkish policies as inflation remains aggressively high.

The Role of Energy Prices

Driven by the war in Ukraine, energy inflation is pushing up the cost of living around the world.

Since October 2020, an index of global energy prices—made up of crude oil, natural gas, coal, and propane—has increased drastically.

Double-Digit Inflation

Compared to the 2021 average, natural gas prices in Europe are up sixfold. Real European household electricity prices are up 78% and gas prices have climbed even more, at 144% compared to 20-year averages.

Amid global competition for liquefied natural gas supplies, price pressures are likely to stay high, even though they have fallen recently. Other harmful consequences of the energy shock include price volatility, economic strain, and energy shortages.

“The world is in the midst of the first truly global energy crisis, with impacts that will be felt for years to come”.

-Fatih Birol, executive director of the IEA

Double-Digit Inflation: Will it Last?

If history is an example, taming rising prices could take at least a few years yet.

Take the sky-high inflation of the 1980s. Italy, which managed to combat inflation faster than most countries, brought down inflation from 22% in 1980 to 4% in 1986.

If global inflation rates, which hover around 9.8% in 2022, were to follow this course, it would take at least until 2025 for levels to reach the 2% target.

It’s worth noting that inflation was also highly volatile over this decade. Consider how inflation fell across much of the rich world by 1981 but shot up again in 1987 amid higher energy prices. Federal Reserve chair Jerome Powell spoke to the volatility of inflation at their November meeting, indicating that high inflation has a chance of following a period of low inflation.

While the Federal Reserve projects U.S. inflation to fall closer to its 2% target by 2024, the road ahead could still get a lot bumpier between now and then.

3D Map: The World’s Largest Population Density Centers

What does population density look like on a global scale? These detailed 3D renders illustrate our biggest urban areas and highlight population trends.

A 3D Look at the Largest Population Density Centers

It can be difficult to comprehend the true sizes of megacities, or the global spread of 8 billion people, but this series of population density maps makes the picture abundantly clear.

Created using the EU’s population density data and mapping tool Aerialod by Alasdair Rae, the 3D-rendered maps highlight demographic trends and geographic constraints.

Though they appear topographical and even resemble urban areas, the maps visualize population density in squares. The height of each bar represents the number of people living in that specific square, with the global map displaying 2km x 2km squares and subsequent maps displaying 1km x 1km squares.

Each region and country tells its own demographic story, but the largest population clusters are especially illuminating.

China vs U.S. — Clusters vs Sprawl

Zooming into the most populated country in the world, China and its surrounding neighbors demonstrate massive clusters of urbanization.

Most people are familiar with the large density centers around Hong Kong, Guangzhou, and Shanghai, but the concentration in central China is surprising. The cities of Chengdu and Chonqing, in the Sichuan Basin, are part of a massive population center.

Interestingly, more than 93% of China’s population lives in the Eastern half of the country. It’s a similar story in neighboring South Korea and Taiwan, where the population is clustered along the west coasts.

The U.S. also has large population clusters along the coasts, but far more sprawl compared to its Asian counterparts. Though the Boston-Washington corridor is home to over 50 million residents, major centers spread out the population across the South and the Midwest.

Clearly visible are clusters in Florida (and not exclusively focused around Miami like some might believe), Illinois, Georgia, and Texas. The population is sparse in the West as expected, but California’s Los Angeles and Bay Area metros make up for the discrepancy and are just behind New York City’s density spikes in height.

India & Southeast Asia — Massive Density in Tight Areas

population density spikes around India

Click here to view the high resolution version.

At 1.38 billion people, India’s population is just behind China’s in terms of size. However, this sizable population fits into an area just one-third of China’s total land area, with the above map demonstrating what the same amount of people looks like in a smaller region.

On one hand, you still have clear clusters, such as in Mumbai, New Delhi, Kolkata, and Bangladesh’s Dhaka. On the other, there is a finite amount of room for a massive amount of people, so those density “spikes” are more like density “peaks” with the entire country covered in high density bars.

However, we can still see geographic trends. India’s population is more densely focused in the North before fading into the Himalayas. Bangladesh is equally if not more densely populated, with the exception of the protected Sundarbans mangrove forest along the coast. And Pakistan’s population seen in the distance is clustered along the Indus River.

population density spikes in Southeast Asia

Click here to view the high resolution version.

Geographic constraints have always been the biggest deciding factor when it comes to population density, and nowhere is this more apparent than Southeast Asia.

Take Indonesia, the fourth largest country by population. Despite spanning across many islands, more than half of the country’s 269 million inhabitants are clustered on the single island of Java. The metros of Jakarta and Surabaya have experienced massive growth, but spreading that growth across oceans to entirely new islands (covered by rainforests) is a tall order.

When the distance is smaller, that cross-water growth is more likely to occur. Nearby in the Philippines, more than 100 million people have densely populated a series of islands no bigger than the state of Arizona.

Indeed, despite being one of the most populated areas in the world, each country in Southeast Asia has had its own growing problems. Some are limited by space (Singapore, Philippines), while others are limited by forests (Thailand, Vietnam).

A World of Different Density Pictures

Though the above maps cover the five most populated countries on Earth, accounting for nearly half of the world’s population, they only show a small part of the global picture.

As the full global density map at the top of the page highlights, the population patterns can accurately illustrate some geographic patterns and constraints, while others need further exploration.

For example, the map clearly gives an outline of Africa and the sparse area that makes up the Sahara Desert. At the same time, landmasses like Australia and New Zealand are almost invisible save for a few clusters along the coast.
